Description Premysl Paska 2008-03-03 19:13:30 UTC

Version:           3.5.0 (using KDE 3.5.8)
Installed from:    Gentoo Packages
Compiler:          GCC 4.1.2 CFLAGS="-march=pentium4 -O2 -pipe"
OS:                Linux

this may be another duplicate of bug 123267, but it was fixed 18 months ago and my system is quite up do date (no Gentoo ebuild for KDevelop 3.5.1 yet)

The description:
I have an open project.
I open File-Select-Replace and enter the following:
  Text to find: FindactiveBranch
  Replacement text: FindActiveBranch
  [x] Case Sensitive
  (x) Whole Words Only
  (x) All files
I click Find, 5 occurrences in two files are found
I keep all selected and click Replace
KDevelop Crashes with the following back-trace:

reproducible: yes
(in most cases it does not crash, but if it does in a case, it does crash always)

I can provide the sources on which it crashes.

Comment 1 Premysl Paska 2008-03-03 20:18:59 UTC

I've tested the circumstances a little more. As said in https://bugs.kde.org/show_bug.cgi?id=123267#c3 it helps when some tabs are closed (not necessarily all of them), but when you open them again it keeps going.

I have observed the following condition required for the crash: There must be at least two open tabs and no tabs are closed since the project was opened (with restoration of the open tabs). And the open tabs must include at least one of the files affected by the replacement. On the other hand, you can open a new tab after opening the project and it still crashes.

Quite strange circumstances... :)

Comment 2 Andreas Pakulat 2008-03-03 21:36:16 UTC

As far as I can see it is a duplicate. If it still happens for you you should file a bugreport for kate, as this is not a kdevelop problem but a kate bug.

*** This bug has been marked as a duplicate of 123267 ***

Comment 3 Premysl Paska 2008-03-03 22:04:20 UTC

Yes, it still happens and I've spent about two hours testing its circumstances.

If it is a bug in Kate, can you please report it? It's KDevelop which crashes not Kate and I don't know what libraries does KDevelop use...

Comment 4 Andreas Pakulat 2008-03-03 23:10:46 UTC

Sorry, but as I can't reproduce it, I can't report any bug. And its also not kdevelop that crashes, but the embedded katepart editor. It just happens to take kdevelop with it when it crashes. You can clearly see that from the backtrace.

So please report this with proper version info against the katepart component.

Comment 5 Premysl Paska 2008-03-04 00:08:14 UTC

Created attachment 23775 [details]
a bzipped project on which it crashes

This should help with reproducing the bug.

(You did not say that you couldn't reproduce it, you said that it is a
duplicate.)

I've got KDE 3.5.8. How can I get a "proper version info against the katepart"
?

Comment 6 Amilcar do Carmo Lucas 2008-03-04 00:52:28 UTC

Start kate on a console.
Then goto the menu and select "Help -> about".
That will give you the katepart version number.

Comment 7 Premysl Paska 2008-03-04 01:35:51 UTC

It says Kate 2.5.8 (Using KDE 3.5.8).

(I thought that it is fully determined by the KDE version, but I understand that it is possible to use a different version.)

Comment 8 Andreas Pakulat 2008-03-04 09:29:32 UTC

Can't reproduce any crash with that sample project either.

Comment 9 Premysl Paska 2008-03-04 14:11:34 UTC

Now I've found out that you must have the option "Remove trailing spaces" enabled to reproduce it

Please try it again with it enabled, the option is accessible from Settings -> Configure Editor..., in the dialog it is the section Editing, almost at the bottom.

(It was suspicious to me, why a function named removeTrailingSpace segfaults...)

Comment 10 Andreas Pakulat 2008-03-04 15:03:57 UTC

I also tried that as its also mentioned in the original report. However it still works fine over here. I even opened up all of the files in the project and added some whitespace to some of them.
