Description Markus 2010-03-31 12:40:36 UTC 
Application that crashed: kdevelop.bin
Version of the application: 3.9.99 (using KDevPlatform 0.9.99)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I can't reproduce this crash, but here is what i've done before the crash:

- Some Files opened, about 15
- removed a folder in the generic project manager with files in it of which some were still opened in kdevelop
- crashed, but on restart of kdevelop the folder was gone as expected


 -- Backtrace:
Application: KDevelop (kdevelop.bin), signal: Segmentation fault

Comment 1 Andreas Pakulat 2010-03-31 14:47:54 UTC 
I'm sorry, the backtrace doesn't provide any useful information (the folder object cannot be null, as the url() call before apparently suceeded) and if its not reproduceable we cannot really do anything about it.
Comment 2 Markus 2010-05-04 11:08:59 UTC

New crash information added by DrKonqi

Just got a crash with the same error / backtrace, but haven't got any files opened in kdevelop.

(generic project manager)

- I realoaded a parent folder of the one i wanted to delete
- right click delete on a folder with other folders and files in it
- crash

I think the reaload was finished before I clicked on delete, but I am not sure about that. If not, it might be related to Bug 224337 ( https://bugs.kde.org/show_bug.cgi?id=224337 )

Hope it helps...

New crash information added by DrKonqi

Same as above: generated a new folder, generated a file in this folder, opened the file, deleted the folder with the file still opened, crash.
Comment 4 Niko Sams 2010-05-18 08:57:51 UTC 
This must be a valid issue, the exact same backtrace three times.
I'll try to make it reproducable with a unittest.
Comment 5 Niko Sams 2010-06-25 10:34:31 UTC 
Very hard to reproduce, but I just got this crash too.
- Generic Project Manager
- Git (but no git plugin installed)
- NFS

Comment 13 ravloony 2011-10-26 22:06:06 UTC 
This is still happening every time I try to open a project file in a git tracked project. I tried removing the svn plugin from kdevplatform source and the relevant CMakeLists.txt and recompiling kdevplatform and kdevelop, but it still crashes. This is strange because the priject in question is not tracked in svn at all.
