Bug 307179

Application: kdevelop (4.3.1)
KDE Platform Version: 4.9.1 "release 561"
Qt Version: 4.8.3
Operating System: Linux 3.4.6-2.10-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

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

Starting application

I have sessions and file sets configured so it could be crashing trying to load those. This behavior started after updating. I was able to get kdevelop to start yesterday after crashing once.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
