Application: kdevelop (4.0.0 (using KDevPlatform 1.0.0))
KDE Platform Version: 4.5.00 (KDE 4.5.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-24-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

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

I went from the screen saver directly to KDevelop code editor. KDevelop refuses to accept keyboard input and crashes when closed from the menu option.

The crash can be reproduced every time.

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