Description Łukasz Kucharski 2011-09-27 06:08:02 UTC 
Application: kdevelop (4.2.60)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 3.0.0-1-686-pae i686
Distribution: Debian GNU/Linux unstable (sid)

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


Switched from one active session to another. Everything seemed to open just right (tabs with source codes and such). But it crashed suddenly. Every restart of the application gives the same result - segmentation fault.

I think it is something project related, never the less it should not lead to segfaults.

KDE libraries come from debian packages and KDevelop was compiled from latest git sources.

The crash can be reproduced every time.

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

Can you remember what project was it? Can you reproduce?
Comment 2 Andreas Pakulat 2012-02-08 15:28:49 UTC 
Backtraces ending in stuff like QList::append etc. usually point to either a binary compatibility, a memory corruption or a null-pointer on the object that has the list as member. The latter is probably not the reason here since the code accesses other members first. So a valgrind log and reproduction recipe are necessary here.

Sorry for not providing the needed info.
