Application that crashed: krunner
Version of the application: 0.1
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-trunk-686 i686
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
when trying to start application louncher (command line run by Alt+F2), it crashes and does not even for a while appeare on the screen. Only the bug assitent apperars after a while.
Furthermore it does not start at all by pressing Alt+F2, but key shortcuts generally do not work.
I run kde 4 on Debian testing (squeeze) on a AMD Athlon X2 machine using, however, 32bit (not 64bit) version of the operation system.
