Application that crashed: krunner
Version of the application: 0.1
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-gentoo-r5 x86_64

What I was doing when the application crashed:
Pressed Alt-F2 shortly after logging into KDE (startup song hadn't played yet), typed a command, pressed enter, krunner crashed. Not reproducable. 

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