Application: krunner (0.1)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-24-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
From time to time, I got this scenario :
- Press Alt+F2 to get application launcher
- Type in a command,
- Not founding what I'm searching for, I press ESC,
- The window disspears, so I go back to the windows I was using,
- The crash appears as per attached backtrace.

I'm on KUbuntu 10.04 with latest updates and DE 4.4.2



The crash can be reproduced some of the time.

 -- Backtrace:
Application: Run Command Interface (kdeinit4), signal: Segmentation fault
