Bug 242153

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:
If a search for a match of a string is in progress, and [Enter] is pressed, KRunner crashes consistently. Even if the search seems to have completed, it often will crash.

 -- Backtrace:
Application: Run Command Interface (kdeinit4), signal: Segmentation fault
