Bug 268994

Application: krunner (0.1)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic x86_64
Distribution: Ubuntu 10.10

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

I was maximizing Konsole.
This also happens at other seemingly random times. But always when I am doing something in the window manager. Like resizing or moving a window.

The crash can be reproduced some of the time.

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