Bug 250257

Application: krunner (0.1)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-trunk-686 i686
Distribution: Debian GNU/Linux testing (squeeze)

-- Information about the crash:
When I tried to open Kontact via KRunner the string completion suddenly stopped and KRunner crashed. Launching Iceweasel in the same way one minute before worked fine. I've noticed similar crash by trying to open Icedove with KRunner, which happened to me approx. 10 times, but bugtracking system have never created a useful report.

The crash can be reproduced some of the time.

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