Bug 244476

Application: krunner (0.1)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-23-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
The Fast Opener- is it Kicker? crashes while entering a Search String. I tried to enter "evolution" but I only reached the first three chars "evo" when the app began to hang. It hang and I did nothing except to wait for a response. After maybe 10s I clicked the big X to cancel the entering process. Then it took another 10s and the app crashed and the Bug Tracker application began its work...

This happens again and again from time to time. I have no idea why. I didn't modify the Fast Opener. I didn't touch the application or modified it.

Regards,
Semox

The crash can be reproduced some of the time.
