Application: krunner (0.1)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-20-generic x86_64
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
I tried to calculate the simple furmula 3000/88= and nothing happened when I typed that in and waited. The calculator worked some minutes before though. I was puzzled and tried 3000/1=, nothing happened. So I tried something like 3000*1= and might have pressed return afterwards. Result: boom.

BTW: Seems like KRunner crashes every now and then on my system (without any backtrace) at least it sometimes doesn't react to Alt+F2.

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