Application that crashed: krunner
Version of the application: 0.1
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-14-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Pressed Alt+F2 to launch krunner, typed a few letters => crash. Only happened once, not easy to reproduce.

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