Bug 292012

Application: krunner (0.1)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-5-686 i686
Distribution: Debian GNU/Linux 6.0.3 (squeeze)

-- Information about the crash:
It seems intermittent, but possibly related to a lot of swap activity.

I'm running Debian 6, with Firefox backported to -release

The crash can be reproduced some of the time.

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