Description Sasa Kara 2011-09-22 12:01:35 UTC 
Application: kdevelop (4.2.3)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

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

I had the computer shut down unexpectedly and when I restarted KDevelop, it crashed on startup with a question whether I want to restore a file from a backup. Before I could answer it, it crashed. I tried starting it another time and it didn't crash.

The crash does not seem to be reproducible.

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