Application: krunner (0.1)
KDE Platform Version: 4.4.1 (KDE 4.4.1) "release 227"
Qt Version: 4.6.2
Operating System: Linux 2.6.31.12-0.1-desktop i686
Distribution: "openSUSE 11.2 (i586)"

-- Information about the crash:
As Above.

This could be related to the bug 223001,but I am not sure.In a way all the krunner crashes may be related as krunner was one component which was solid in KDE 4.0 till kde 4.4.x series came.But that is for developers.

The strange behaviours I notice with krunner after update to kde 4.4.x is,inexplicably it stops appearing.I cannot call krunner either with alt+f2 or 'run a program' after sometime into a kde session.I cannot link that to any particular event.

The crash can be reproduced some of the time.
