Bug 314935

Application: krunner (0.1)
KDE Platform Version: 4.10.00
Qt Version: 4.8.4
Operating System: Linux 3.7.4-gentoo x86_64
Distribution (Platform): Gentoo Packages

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

After hitting Alt+F2 and typing a few letters Krunner crashes. This happens quite often (but not always).

The crash can be reproduced some of the time.

-- Backtrace:
Application: Run Command Interface (kdeinit4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
