Application that crashed: krunner
Version of the application: 0.1
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.6.0
Operating System: Linux 2.6.31-gentoo-late64 x86_64

What I was doing when the application crashed:
after fresh login to kde-4.3.4, alt-f2 to fire up krunner. As soon as I type something in it, krunner segfault.

I'm running Gentoo GNU/Linux amd64 with freshly installed kde-4.3.4
