Description Dmitry 2013-05-31 03:43:38 UTC 
Application: kdevelop (4.5.0)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-21-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
1. Open git controlled project in KDevelop
2. open some source files to edit
3. Perform git checkout my/other/branch to provoke massive file change
4. Kdevelop crashes (sometimes)

Unfortunately I haven't detected any dependency between actual files being edited and branches being switched so this looks like unrelated race condition that may be triggered by any file change.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Comment 1 Dmitry 2013-05-31 03:45:32 UTC 
Please note that git checkout is performed in a terminal, i.e. not using builtin git support plugin.
Comment 2 Aleix Pol 2013-05-31 11:12:43 UTC 
It doesn't really make a difference it being on a terminal...

Can you reproduce that problem? I don't think there's much we can do about this now... Actually it crashes in your nvidia drivers.
Comment 3 Dmitry 2013-06-10 11:16:01 UTC 
It happens quite often which is annoying. Unfortunately, I was failed to find a reproducible way to crash kdevelop.
Comment 4 Chao Feng 2013-06-21 09:27:10 UTC 
Please try out a open source NV driver and check again. The crash is in the driver from back trace.
Comment 5 Christoph Feck 2013-06-24 10:19:33 UTC 
Please valgrind the issue, if it is reproducible.

The nvidia driver is involved in memory management, but if the memory is corrupted by the process (e.g. by a bug in kdevelop), it sometimes looks like the crash was in the nvidia driver.
