Description Kevin Adler 2012-03-21 17:50:25 UTC 
Application: kate (3.8.1)
KDE Platform Version: 4.8.1 (4.8.1) "release 481"
Qt Version: 4.8.0
Operating System: Linux 3.1.9-1.4-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

I opened a save dialog to save a new file. After that, Kate became unresponsive. Finally, the save dialog came up. I tried to change the file name, but it was apparent the save dialog was unresponsive. I left it be for a while, periodically checking responsiveness. Eventually, it just crashed.

-- Backtrace:
Application: Kate (kdeinit4), signal: Segmentation fault

gwenview (2.8.1) on KDE Platform 4.8.1 (4.8.1) using Qt 4.8.0

Gwenview and also dolphin are quite unstable! If running both, crashes occur regulary!

As I posted a separate bug report which was noted a duplicate of this one, I do post some debug info here!!

Bug #296537 comment #2 contains steps how to reproduce:

> 1. Launch kdevelop
> 2. On another konsole window, run "umount -a"
> 3. Enjoy the crash.
> 
> I use automount, so this crash happens every few minutes, so I am not able to use Kdevelop anymore.
Comment 6 Kevin Adler 2012-04-06 21:58:54 UTC 
I just tested again on 4.8.2 and I'm no longer getting this problem.

1. mount cifs client
2. open file in mounted directory in kate
3. umount directory

I got 'The file ... was deleted by another program' dialog like it normally would, instead of crashing.

New crash information added by DrKonqi

dolphin (2.0) on KDE Platform 4.8.2 (4.8.2) "release 491" using Qt 4.8.1

- What I was doing when the application crashed:
dolphin was open on a mounted nfs directory, then networkmanager restart the connection (or systemd, for no good reason)
Dolphin start to crash with a very minimal error 

Application: Dolphin (kdeinit4 (deleted)), signal: Segmentation fault
[Current thread is 1 (process 19877)]

Thread 1 (process 19877):
#0  0x874a68dd in ?? ()

And then I get this new crash.

So there's something that can't handle correctly the fact a network connection could be drop. The program should avoid to crash so badly.

I dont mean to rush since I understand this is open source software and developed mostly as community service. 
But wouldnt it be nice to hear of atleast a workaround for such a critical bug ?
Having Kdevelop crash every 2 minutes is definitly a blocker to its success or even adoption.

On the technical side, I dont see any issue with Kate, but only with Kdeveop. Yet this crash keeps getting duplicated to a bug titled ".. kate ...".
Kate is just an editor. Users can temporarily switch to another easily. Things are not so sweet with kdevelop. Its an IDE too good to have a replacement. 
So titling this bug as a bug in an editor kind of belittles its importance. Dont you think ?

This one should be fixed by:
https://git.reviewboard.kde.org/r/104471/
Fix should be in 4.8.4, openSUSE has it cherrypicked:

rpm -q --changelog libkde4 | grep fstabstorageaccess
- fix crash due to race in fstabstorageaccess constructor

As a temporary workaround, it might be enough to disable the places view in the open dialog.
Comment 19 Pradeep K. Shima 2012-05-10 11:25:02 UTC 
Thanks a lot for the response Stefan,

About the fix : You mean version 4.84 of kdelibs ?

About the workaround : which "open dialog" ? I see the crash in Kdevelop without doing anything. the bugs title is way too misleading.

This bug was specifically about the file dialog in kate, and the same bug can also be seen in dolphin, as it uses the same "Places" side pane.

You never submitted a backtrace, so you may be hitting a completely independent bug.
Comment 21 Pradeep K. Shima 2012-05-10 14:58:18 UTC 
Thats quite unfortunate. 
The bug was very much reported on Kdevelop by me along with backtrace (Bug #296537)
But Someone or some = tool keeps marking it as a dup of this bug. 

I added comments on this bug to show criticality of the issue and impact I am facing every few minutes but alas this bug is still titled as a simple bug in an editor :(

This information would have been useful in the first place - and yes, it is a duplicate (as can be seen from the backtrace).

KDevelop must have a "Places" pane somewhere.
Comment 23 Pradeep K. Shima 2012-05-23 08:40:52 UTC 
Disabling the Filesystem Tool View in Kdevelop is a workaround that seems to work.
Right click on teh Filesystem toolview and click "Remove Toolview".

That aligns with the above comment "KDevelop must have a "Places" pane somewhere."

New crash information added by DrKonqi

k3b (2.0.2) on KDE Platform 4.8.3 (4.8.3) using Qt 4.8.1

- What I was doing when the application crashed:

waiting for a burn to finish (it was done or very nearly done when the crash happened)
ISO image file was on an NFS mount, if that matters (as has always worked in the past).
