Application that crashed: krunner
Version of the application: 0.1
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.1
Operating System: Linux 2.6.28-gentoo-r6 x86_64

What I was doing when the application crashed:
Krunner crashed when I was trying to start virtualbox by typing virtualbox into krunner.
I think it crashed around the "virt" part. The only peculiar thing I can think of is that I once had the nepomuk and strigi stuff enabled, but currently it is disabled. Perhaps krunner tried to access some nepomuk data when it was searching for "virt"? (at least, next to virtualbox, it also showed kdevelop in the results).

Regrettably I am not able to reproduce this crash so far
