Bug 310014

Application: kdevelop (4.4.60)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.5.0-18-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
I had two projects open when I closed kdevelop. I did a restart of my computer and then In tried to start kdevelop. It crashed twice in a row while during application startup. The third time it worked again.

The crash can be reproduced some of the time.

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