Bug 240098

Application: krunner (0.1)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
As written above, KRunner crashes sometimes.

I tried several ways (waiting for loading whole list of nepomuk, hitting enter shortly twice, ...) but I found no posibility to repeat this behavior.

Differences of my kde to standard one:
- using asoundrc to access both soundcards at same time
- using 6 desktops with different bg-images and plasmoids
- using startup script to prevent akonadi starting after / during kontact startup

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Oberfläche zur Ausführung von Befehlen (kdeinit4), signal: Segmentation fault
