Description Peter Hedlund 2003-12-09 04:10:06 UTC 
Version:           3.0.0b2 cvs 2003-12-07 (using KDE KDE 3.1.4)
Installed from:    Mandrake RPMs
Compiler:          gcc 3.2.2 Mandrake Linux 9.1
OS:          Linux

When opening an existing project in KDevelop (continuosly updated from cvs, most recently 2003-12-07) the program appears to load fine and loads the project files, but when the updating progress bar reaches 100% KDevelop crashes. This behavior started to appear some weeks ago. I get the following backtrace:

This behavior is not the same as 69423. Deleting the file MyProject.kdevelop.pcs prevents the crash, but the file is recreated when exiting KDevelop making it crash again next time.
Comment 1 Andy Neitzke 2003-12-10 23:42:49 UTC 
I am seeing precisely the same symptoms.  My backtrace looks a little different though (this is with kdevelop and kdelibs compiled from CVS just now, with enable-debug=full):

Comment 2 Andy Neitzke 2003-12-11 01:12:34 UTC 
Sorry, I'm an idiot:  after correctly updating my CVS version I don't see this bug anymore.
Comment 3 Jens Dagerbo 2003-12-13 16:42:40 UTC 
This report comes in from all over the place, so it should be real enough..

http://www.kdevelop.org/forum/read.php?f=2&i=10127&t=10127
http://lists.kde.org/?l=kdevelop-devel&m=107083560503928&w=2

The common things we can see is that all reporters seem to be using Mandrake and KDE-3.1.x

Is anyone seeing this crash on a different setup? Also, what are your Berkeley DB versions?
Comment 4 Jens Dagerbo 2003-12-13 16:46:16 UTC 
Ignore the Berkeley DB question, it should not be relevant. Qt version could be though.
Comment 5 Peter Hedlund 2003-12-13 22:05:11 UTC 
I have Qt 3.1.2, it's the packages libqt3.1.2-9.2tex, libqt3-common-3.1.2-9.2tex, and libqt3-devel-3.1.2-9.2tex.

The Berkeley DB are stock for Mandrake 9.1:
Name: libdbcxx3.3
Version: 3.3.11-13mdk
Name: libdb3.3-devel
Version: 3.3.11-13mdk

Comment 8 Jens Dagerbo 2003-12-17 00:07:23 UTC 
This crash seems quite common, but I have yet to see it reported from anything else than a Mandrake install..
Comment 9 Sebastien 2003-12-22 13:33:28 UTC 
I have the same bug :

In past, I was have Mandrake 9.1 and then upgraded from KDevelop 2.5 to Gideon Alpha7.
I've resolved this bug by removing all the KDev config files.

Then, this week-end I've upgraded to Mandrake 9.2, and then to KDevelop beta2.
This bug have reappared and I've just created a new project and then open my old project : the bug has now dissapeared for me...

I'm still getting this crash with the latest Mandrake Cooker packages.  Running with gdb gives some information that might be useful to someone:

Comment 15 Sebastien 2004-01-21 19:30:06 UTC 
I've donloaded KDevelop RC1 and this Crash is now systematic (It crash when a project is fully loaded (when create a project, it doesn't crash)) !!!
I've then browse the code to find what's wrong...

In projectmanager.cpp :
  Core::getInstance()->doEmitProjectOpened();
Seem to be the source of the crash because it Crash just after calling that.
So, it's crashing in one of the slots.
I've checked MainWindow::slotReactToProjectOpened()
but after the execution of it (juste before return) it doesn't crash !
So it's after...

I then have commented this line :
  Core::getInstance()->doEmitProjectOpened();
(just before "return true;")

Now, it don't crash anymore.
But if I change project, still incoherence...
It isn't grave because I have only one project with KDevelop.

* Is anyone can say what's crash (I've KDE 3.1.3 on Mdk9.2 : perhapse a resolved crash with HEAD KDE libs).
* For those who are in the same case, can you try to comment this line too?, to see if it's that.
* I don't see any projectOpened() reference in other source files... Strange (or perhapse it crash because of hidden tab ? hum)...
Comment 16 Jens Dagerbo 2004-01-22 01:43:57 UTC 
No, comment #15 is using way too much dynamite.. ;)

I don't have an affected system here, but as a test, could someone try this:

change languages/cpp/cppsupportpart.cpp, line 799 from

 parseProject( );

to

 parseProject( true );

and report back if that helps or not?
Comment 17 Andy Neitzke 2004-01-22 07:27:16 UTC 
The fix in comment #16 seems to work for me.  Thanks!
Comment 18 Jarkko Haapalainen 2004-01-23 04:58:54 UTC 
I have same symptoms here with KDE 3.2-rc1 and I even tried 20042201 snapshots (kdelibs, kdebase, kdevelop). I tried that fix on comment #16, but it didn't help.

I can preproduce this always:
1. start kdevelop
2. open project
3. again, open project
4. -> crash!

And it crash when closing app too:
1. start kdevelop
2. open project
3. quit kdevelop
4. -> crash!

Comment 19 James Gregory 2004-02-04 17:51:53 UTC 
Identical crash here - the blue bar gets to 100% and it crashes.

I'm using Mandrake 9.2, although with KDE 3.2 + Kdevelop 3.0 rpms from Mandrake Cooker.

The KDE crash handler thing that pops up only has one thing on the stack, an error in "waitpid () from /lib/i686/libpthread.so.0".
Comment 20 James Gregory 2004-02-05 05:08:04 UTC 
Hmmmm...it just stopped doing it.

I've been messing with my computer quite a lot today, so I'm not quite sure what I've done that has fixed it (at least for now).

The biggest change I've made to my computer today was probably when I found that I was lacking the non-development standard C++ libraries (not quite sure how that happened) and so I installed them from an rpm. But given I use urpmi and don't really pay much attention to what it's doing, it's quite possible I've changed/updated something else major without noticing. I find it hard to believe everyone here has managed to accidently not install libstdc++.
Comment 21 James Gregory 2004-02-05 07:24:52 UTC 
And now it's started again, even though I haven't changed anything.

Comment 23 stephane martin 2004-02-14 03:38:03 UTC 
I also have this bug with the same symptoms on Mandrake Cooker. I use Qt 3.2.3 and the KDE 3.2 mdk-packages from Cooker. The strange fact is that sometimes Kdevelop crashes when I open an existing project, sometimes it does not crash when opening the same project !?

I have tried to compile and install KDE3.2/Kdevelop from the sources on my mandrake, and the bug is not there anymore...
Comment 24 stephane martin 2004-02-16 02:34:43 UTC 
The replacement in #16 has solved the problem for me. Thank you !!
Comment 25 Hendrik Kueck 2004-02-19 09:01:56 UTC 
I had the same problem here, using Mandrake 10 Beta2 and the change in posting #16 fixed the problem for me as well.
Thanks.
Comment 26 Jarkko Haapalainen 2004-02-19 09:05:59 UTC 
I had same problems with 3.0, but not anymore with 3.0.1. This bug should be closed.
Comment 27 Peter Hedlund 2004-02-20 01:37:07 UTC 
This bug is no longer present in KDE and KDevelop cvs under Mandrake 9.1. As the original reporter I agree that it should be closed.
Comment 28 Daniele Granata 2004-02-26 12:55:57 UTC 
I have the same problem with the latest cooker-rpms on mandrake 10-rc1. KDevelop crashes when loads a project (after the progress bar gets 100%). I changed the editor to QEditor and the bug disappear. I hope will be useful for the mandrake users out there.
Comment 29 Jens Dagerbo 2004-02-26 13:25:14 UTC 
"I changed the editor to QEditor and the bug disappear."

HUH!? That's not at all expected. Could people please try this out and report back if it is really true.

If it really only crashes with katepart ("embedded advance texteditor"), what happens if one closes all editor windows before closing the project? (The next time the project loads, no windows will then be opened (and no katepart editor plugin instantiated).)
Comment 30 James Gregory 2004-02-26 19:27:16 UTC 
Closing all editor windows doesn't help, it still crashes.

I've been getting round the problem by deleting the pcs file of my project each time just before I load KDevelop, if anyone else is looking for a lazy workaround which doesn't involve playing with the source.
Comment 31 Jens Dagerbo 2004-02-26 22:59:24 UTC 
*** Bug 76210 has been marked as a duplicate of this bug. ***
Comment 32 Rudolph Pienaar 2004-02-26 23:11:50 UTC 
Bug should not be closed.

I get the same bug (same basic Mandrake 9.2 setup w / stock mdk-kde install). Built kdevelop-3.0.1 from source / QEditor.

The bug does not appear 100% of the time, on balance I'd say about 80% of startups with a *.kdevelop.pcs present will fail.

Note that in my case I am working on *legacy* projects, i.e. projects that were created with one of kdevelop-3 release candidates.
Comment 33 Sebastien 2004-02-27 17:13:33 UTC 
I've installed KDE 3.2 packages for my Mandrake 9.2, with KDevelop 3.0.0.
My old project was opened well, without crash.
But "classes" side pannel was empty and so, Ctrl+J or Ctrl+Space won't work.
VERY ennoying.
Then, I've downloaded and installed KDevelop 3.0.1.
First start : crash after 100% loading.
I've even removed all config files and then set to QTEditor, and then reopen my project => crash yet exist.
For me, crash appends 100% times !!!

Note: the project load with this Classes working is slower, but it crash.
Perhapse it's the solution : perhapse a bug in the "resence classes and methodes" part (I work on C++/KDE project)...

I also have an error in console AT START OF THE LOADING :
"ASSERT: (part && parent) in partwidget.cpp (41)"
Then the project continue to load, and went to 100%... and crash :-(
Perhapse this Assert is another clue...
Comment 34 Daniele Granata 2004-02-28 17:10:34 UTC 
I'm a lucky guy, my qmake project loads every time with no crash. I'm working with MDK10-RC1 kernel enterprise 2.6.3-3, kdevelop3.0.0-6 and the latest kde libs. I've tried to revert to kate editor with no crash.
I have disabled some secondary stuff like a pair of plugin and other tools.
I cannot be more specific because I use KDevelop at home and type this comment at work.
Try to use a "light" version without the complementary staff i.e uncheck all the plugins, some secondary tools and so on. If you will have no crash then add one plugin at once and the secondary staff at once. Maybe it will work as for me.
If this bug is related only to the mdk version, maybe the best place to add comments is the cooker-ML.
Comment 35 Sebastien 2004-02-28 19:12:23 UTC 
Hey ! Cool :

I've deleted the file with extension .pcs, as said in #32, and it launch very well without crash :-D I can program, after all those months !!! ;-)

What's the purpose of this file ?
For a plugin, certainly (to join #34) ? ...
It contain a lot of sources paths of the project (old paths, because I've moved my project into another folder), classes names and stranges characters !

=> It could be the problem of my old bug (empty "Classes" side pannel and Ctrl+J or Ctrl+Space won't work ; see #33) : because I've moved my files it hasn't found my Classes/methodes, and haven't loaded them => so no crash (I think...).

I thinks it's the problem :
Which plugin recense classes and methods, and why it crash at 100%...
(But why only Mandrake ! ...)

I haven't restarted KDevelop. So I don't know if I will be obligated to redelete this file later.

Hope we will go forward.
Comment 36 nick smethurst 2004-03-01 09:29:11 UTC 
I'm running KDevelop 3.0.1 on Mandrake 9.2 and the parseProject(true); fix suggested in comment 16 has stopped the crashing.
Comment 37 Chris Thompson 2004-03-01 19:32:31 UTC 
I too am running KDevelop 3.0.1 on Mandrake 9.2.  The fix suggested in comment 16 also worked for me.
Comment 38 anton 2004-03-12 22:40:03 UTC 
Still not fixed in a compiled from source 3.0.2, though I am also running a hybrid (9.2 with bits from cooker) MDK system. Is there any reason not to build the #16 fix into the next release (for us MDK lackies here)?
Comment 39 anton 2004-03-12 23:19:40 UTC 
Now I have changed and reinstalled from the sources (sorry, still a newbie, I just edited the file with vi, then reran make and make install, if this is wrong then please hit me :-0). Still no joy, same message as before:

0x41905686 in waitpid () from /lib/i686/libpthread.so.0
#0  0x41905686 in waitpid () from /lib/i686/libpthread.so.0
#1  0x40d2fceb in KCrash::defaultCrashHandler(int) ()
   from /usr/lib/libkdecore.so.4

but this time it was when I clicked on the documentation manager panel (or maybe the file creation one...).
Is this the same bug?

ps. Sorry but I thought I had it fixed too...
Comment 40 Christian Fontana 2004-03-15 00:04:07 UTC 
Also on my slackware 9.1 installation this crash appears. If I'm using a project and I have to load an other one I've to close the project, close Kdevelop, re-run kdevelop and open the other project.
Comment 41 Ertan Deniz 2004-03-18 12:01:46 UTC 
I am using Mandrake 10 Community Edition.

I tried both KDevelop 3.0.0 that's default on Mandrake 10, and KDevelop 3.0.2 that I compiled...

They both crashed when I tried opening my existing projects.

I solved the problem just by disabling "File Selector" plugin.
Now everything works pretty good.
Comment 42 Igal Ore 2004-03-22 21:09:41 UTC 
Here at use Mandrake 10 Community edition ( downloaded ) with Kdev 3.0.1 (default install) had reproduced bug as described : or by marking project to be reloaded automatically next time , or by simply  close/open combination . 

Both solutions from 41 and 30 had worked for me , of cause 41 is better

Comment 44 toussis manolis 2004-03-29 12:52:33 UTC 
I use Mandrake 10 community fresh installed with kernel 2.6.3-4 smp .
kdevelop 3.0.1 kde3.2
I had the same problem. I was making a new project (kde-framework) and then I exited kdevelop. When I open it again kde was crashing when It was ready to give focus... (after all the loading stuff).
I could reproduce the bug consistently.
The solution for #41 has worked for me. I removed file selector from the plugins and now kdevelop works fine.
Comment 45 Jens Dagerbo 2004-03-29 13:15:12 UTC 
OK, that makes three successful reports about removing the FileSelector. I believe it's real now. No wonder we couldn't find it.. something completely unrelated to the PCS system crashes as a result of a filesystem event. And ONLY on Mandrake!

Changing component to FileSelector.
Comment 46 Thomas Aynaud 2004-03-29 19:46:12 UTC 
idem #44, the solution for #41 has worked for me.
Comment 47 Alexandre Beaulieu 2004-04-26 01:41:01 UTC 
I'm using KDevelop 3.0.3 with Mandrake 10.0 Official and KDE 3.2.0. I had the same problem and #41 corrected the crash but led to another bug. Now, all child windows may it be the editor or the tabs do not appear has child windows but as independant windows. All windows are not shown by default even though they are checked in the menu. Removing $HOME/.kde/share/config/kdeveloprc solves this problem but gets back to the crash problem.

Comment 49 Rutger ter Borg 2004-06-22 18:22:59 UTC 
I am experiencing similar crashes with kdevelop-3.0.4, kde-3.2.2, linux-2.6.7-gentoo-r3 on an amd64. Kdevelop crashes systematically, one of every two startups.  I've compiled it in debug mode and ran it through gdb. The behaviour is consistent and can be reproduced.

(gdb) run

Comment 50 Rutger ter Borg 2004-06-22 18:27:35 UTC 
Forgot to mention: If kdevelop does get through, gdb shows the following. The crash seems to reside between the filecreate part and cpp support.

Comment 51 Paul Fotheringham 2004-06-27 02:34:32 UTC 
I had a simlar problem in Mandrake 9.0. It also appeared in Mandrake 10.0 OE PowerPack. I fixed it by removing ~/.kde/share/config/kdeveloprc which was from my old Mandrake 9.0 install and letting kdevelop create a new one.

I can't remember enough details about it though to say for sure whether it's the same bug but it sounds like it.
Comment 52 Rutger ter Borg 2004-06-28 09:48:29 UTC 
Not preventing crash:  comments #41, #51
Successful workaround: comment #30
Comment 53 Brendan 2004-07-01 15:36:33 UTC 
Neither #16, #30, #41, or #51 were able to fix this for me in anyway.

I started noticing the problem with 3.0.1 which I got from a Mandrake 10 RPM (from Mandrake), and which continued from the 3.0.4 source which I built from.

Thinking along the lines of #41, after the disabling of the File Selector plugin did not solve this, I ended up trying it with all plugins disabled which sadly did not solve my problem either.
Comment 54 Rutger ter Borg 2004-07-01 16:49:53 UTC 
I spent some time looking at the code, bearing in mind that the presence of the .pcs file prevents a crash. I'm using the code of kdevelop-3.0.4, and discussing the file languages/cpp/cppsupportpart.cpp. I'm indicating line numbers.

(847) QDataStream stream;

only if a pcs file does not exist (conditional):
(854) stream.setDevice( &f );

later on (either with or without 854 executed):
(904) stream.device()->at( pcs[absFilePath].second );

This (904) occurs without a check for a valid stream, i.e. it could also be unset. I am not familiar enough with Qt to known whether this statement will cause a crash, nor am I able to recompile right now.
Comment 55 Rutger ter Borg 2004-07-01 16:56:18 UTC 
I meant the other way around, "bearing in mind that the absence of a .pcs file prevents a crash"
Comment 56 jtwatson 2004-08-20 04:13:39 UTC 
I am running Mandrake 10.0 Official.  I can confirm that Kdevelop will crash when opening a exiting project that contains a .pcs file.  If this file is deleted it will open the project again.  I have reproduced this on 3.0.0 (mandrake rpm), 3.0.4 (mandrake rpm), and 3.0.92 (compiled from src). 

Comment 41 disabling "File Selector" plugin definitely fixes this for me.  It has never crashed on startup when opening a project that contains a .pcs since.

I can still make it crash by using the Project Menu to Close and Open projects, but I think this is a different problem and seams unrelated to the .pcs files.
Comment 57 Ray Glover 2004-08-22 13:49:18 UTC 
Using Mandrake 10.0 as #56. I get the following console messages if these mean something to anyone:

Comment 58 Jens Dagerbo 2004-08-29 02:52:49 UTC 
I've seen reports that this problem has disappeared in KDevelop-3.1. Can anyone here confirm?
Comment 59 Hendrik Kueck 2004-08-29 03:07:21 UTC 
Yes, I can confirm that. I had the problem with previous versions and fixed it with the patch you proposed in comment #16 at the time. 
Kdevelop 3.1 worked right out of the box for me.

*** Bug 88721 has been marked as a duplicate of this bug. ***
Comment 61 James Gregory 2004-09-07 20:19:27 UTC 
Nope, sorry, 3.1 did not fix it for me. #16 and #30 both continue to work. Although #16 now refers to line 917.

Would it be possible to add an option to ./configure that automatically compiles with #16 using #ifdefs? This seems to effect enough people that an automatic workaround for now might be nice.
Comment 62 David Lindsey 2004-09-15 12:10:37 UTC 
I can confirm #61 (partially). Using Mandrake 10 I had the problem with Mandrake rpms. I downlowded and compiled 3.1.0 from kdevelop.org and still have the problem. #30 works. Have not yet tried #16.
Comment 63 Rutger ter Borg 2004-09-28 20:42:29 UTC 
I can confirm #61 as well, compiled on gentoo on an amd64. #30 still works.
Comment 64 Rutger ter Borg 2004-10-01 14:07:05 UTC 
Version info: kdevelop 3.1.0, kde 3.3, qt 3.3.3, gcc 3.3.4, amd64

Kdevelop 3.1.0 keeps crashing very regularly on exact the same places as kdevelop 3.0.4. The first type is once in every two times of starting the program, which is the bug discussed here. However, kdevelop also crashes when closing a tab of a loaded project, and starting recompile. In both occasions, the "Updating..." is the last visual feedback. 

I've recompiled kdevelop with debug enabled to find more details. Unfortunately, tracebacks keep to be too corrupt to be useful. Anyway, the last debug statements of the startup-type crash are

kdevelop (cpp support): CppSupportPart::parseProject 1

Comment 65 Rutger ter Borg 2004-10-01 17:36:21 UTC 
I have found the bug causing the crashes. In short: the kdevelop gets stuck in an infinite recursive loop in ClassModel::read where it calls that same function over and over again from line 932 of codebase 3.1.0. By adding debug statements, I tracked the path of the crash down to the following:

bool CppSupportPart::parseProject( bool force )    
void CppSupportPart::slotParseFiles() called from cppsupportpart.cpp #995
void FileModel::read( QDataStream & stream ) called from cppsupportpart.cpp #1025
void NamespaceModel::read( QDataStream & stream )  
void ClassModel::read( QDataStream & stream )
*CRASH*

Below some (maybe not so useful) backtraces. This first one is without added debug statements in the classmodel::read, the single-shot timer in #21 is the one at the end (last statement) of the parseProject() code.

Comment 66 Rutger ter Borg 2004-10-01 19:26:48 UTC 
Maybe I experience frequent crashes because of the native 64 bit environment. FWIW, I think all offsets (JobData::pcs::second) in cppsupportpart.cpp and cppsupportpart.h should be of type QIODevice::Offset, and not Q_LONG or Q_ULONG (which is clearly undesirable). I.e. in cppsupportpart.h 

QMap< QString, QPair<uint, QIODevice::Offset> > pcs;

and at several places in cppsupportpart.cpp.

As a second note, the value of
_jd->pcs[absFilePath].second

in 

~line 1025: _jd->stream.device()->at( _jd->pcs[absFilePath].second );

gives an offset of 27676769255424 at the time of the crash. The filename is valid, as is the timestamp. Perhaps the offset isn't stored correctly at the time of creation of the .pcs file?

This is a quick fix for the crashes on amd64. Q_LONG and Q_ULONG offsets in
cppsupportpart are replaced by 32-bit unsigned ints in this hack.
Comment 68 Brian Martin 2004-10-25 23:56:17 UTC

Comment 71 Harry 2004-11-13 13:45:04 UTC 
KDevelop 3.3.1 or KDevelop 3.3.0, KDE 3.0,SuSE 9.2, x86_64
starting Kdevelop -> loading an C++ project -> KDevelop crashes
starting KDevelop once more and loading the same project, everything works fine.

i can reproduse this behavior several times - on every "odd" start KDevelop crashes, on every "even" start loading an project succeeds.

switch to QEditor has no effect.

sounds funny but is the truth.

As confirmed by PreviewJob in the backtrace, this was due to a KFileDialog bug which would let PreviewJob use a deleted KFileItem [so it only happened when activating icon mode and previews in the file dialog].
I just fixed this in kfileiconview.cpp 1.100, hopefully just in time for 3.4.

Comment 79 Giovanni Venturi 2005-07-06 23:03:41 UTC 
Opening my KDevelop Project KDevelop crashes. This happened after the KDE 3.4.2/KDevelop 3.2.1 SVN installed. This doesn't happened with KDE 3.4.1/KDevelop 3.2.2.

Comment 85 RADHIKA 2005-11-30 21:00:23 UTC 
I get the same bug,  i am totally stuck with my work progress. As soon as I try to one of the exisiting project in which I have added my own files, kdevlop crashes.  I am using Fedora Core 4, I dont know the exact version of kdevlop but its the one which comes with fedorea core 4, I havent upgraded it yet.
The backtrack report is as follows:

Maybe it's time for you to update ....
Comment 87 Tim Harper 2006-01-28 01:03:52 UTC 
when I load this file in ruby source in kdevelop, it crashes (must be when it is parseing the code?) :

#!/usr/bin/env ruby

class Foo
	attr_reader :name
	attr_writer :name
	
	
	def my_methood
	end
	
	def what_is_my_name
	@name = chris
	end
	
	def return_name
	return @name
	end
	
	self.my_public
	global_var = "foo"
	end
	
	private
	def private_methood
	end
end

Foo.what_is_my_name
Foo.name

Foo::my_public

puts "Hello world"

I=50
Comment 88 Tim Harper 2006-01-28 01:05:36 UTC 
note:in my above comment
the crash occurs when I load the project with that code
the project is a ruby project, which contains but one file: buddybin.rb
Comment 89 Jason Taylor 2006-02-20 02:23:09 UTC 
I was a Mandrake user and I had this problem, now use Fedora core 4 and the bug remains.

I am using KDE 3.5.1-0.1.fc4 and KDevelop 3.3.1

When I open an existing project the first time, kdevelop usually crashes. If I open it immediately again, it loads faster and does not crash.

It seems to me that it might be a timing issue.

Comment 90 Nadeem Hasan 2006-03-12 22:18:02 UTC 
For me it crashes a lot at startup and shutdown with the exact same backtrace as above. I am using 3.5.1+ with KDevelop 3.3.1 both compiled from source on SUSE10.
Comment 91 Randall Graham 2006-03-13 06:22:53 UTC 
My suggestion, buy a fast machine and move to eclipse.
You won't look back.

Comment 93 evdsande 2006-04-22 12:50:47 UTC 
This problem still occurs in kdevelop 3.3.2 and is really anoying. In my case it looks related to having a html file open in the project. 
I'm running SuseLinux 10.0 with kdeupgraded to version 3.5.2 which includes kdevelop 3.3.2

Here's my backtrace:

Hello,

I am encountering this bug too, while working on Digikam 0.9-svn (KDE application). Here is a backtrace:

Using host libthread_db library "/lib/tls/libthread_db.so.1".
`system-supplied DSO at 0xffffe000' has disappeared; keeping its symbols.

Comment 97 Sergei 2006-08-29 00:38:08 UTC 
It is seen again :(((

I have a kdevelop version 3.3.4



This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.

(no debugging symbols found)
Using host libthread_db library "/lib/libthread_db.so.1".
Comment 98 Sergei 2006-08-29 00:39:55 UTC 
Happens once again.

Very fast after the begining of the opening the project.

Comment 99 Amilcar do Carmo Lucas 2006-08-29 15:05:54 UTC 
Sergei, please update your KDE to 3.5.4 and your KDevelop to 3.3.4.
The bug you reported is not the one described in this thread and it is solved there.

#98 is fixed for 3.4 (a different bug), for the rest I don't know.

patch fixing a  crash on shutdown

kdevelop uses a few singleton objects that are never deleted on exit, and which
are the "owners" of quite a bunch of other objects. When closing the main
window with Alt-F4 for example, the QObject hierarchy will make sure that
(almost) everything is deleted in the right order. 

When closing kdevelop through session management, or e.g. via "dcop `dcop
kdevelop*` MainApplication-Interface quit" however, kdevelop is being closed
with the last window (and hence all its child objects) still alive.

On KApplication destruction, all the plugins are deleted through KLibLoader:

I'm not exactly sure why this doesn't work (it certainly is not related to
KFileIconView -- if I change its destructor to {} the crash happens in the next
(documentation) plugin.

In order to fix this, kdevelop simply needs to make sure to clean up all its
plugins and singletons in time.

This patch does that in a proof of concept way. I'd rather have a dedicated
QObject though, that manages all those singletons and listens to kapp's
aboutToQuit() signal to perform the shutdown, then. I'm happy to create a new
patch doing this.

In order to verify this, try current kdevelop 3.x and quit it with Alt-F4 once
and with "dcop `dcop kdevelop*` MainApplication-Interface quit". The latter
should make it crash. Now apply the patch and try again.
Comment 103 Matt Rogers 2006-11-04 16:04:30 UTC 
SVN commit 601896 by mattr:

Apply patch from Carsten Pfeiffer to fix crashes on KDevelop shutdown.
This patch fixes crashes in the following two situations:

- Quit via the command 'dcop kdevelop-1234 MainApplication-Interface
  quit'
- Quit when closing as part of KDE logout

Thanks for the patch!

Comment 104 Megan Webb 2006-11-05 00:06:10 UTC 
This bug has become a basket case of many crashes.

- The original crash was fixed. 
- The versions of kdevelop, kde have all changed over the time of this bug report.
- Several of the other reported crashes (not relating the the original report) have been fixed.
- The jumble of many different bugs in this one report makes it impossible for us developers to deal with.
- The last reported crash has had the patch committed to svn.3.4 branch 

Ideally, if anyone can test on svn version 3.4, that would be great. 

Regardless, of if you can test on svn version 3.4 or not, if you still have a problem can you file a new bug report with a backtrace so we can find out the if a problem still exists.
