Description Viktor Havrysh 2010-01-31 11:50:29 UTC

Application: krunner (0.1)
KDE Platform Version: 4.3.95 (KDE 4.3.95 (KDE 4.4 RC2))
Qt Version: 4.6.1
Operating System: Linux 2.6.32-ice i686
Distribution (Platform): Archlinux Packages

-- Information about the crash:
I installed 4.4 RC2 yesterday, and krunner already crashed twice. Once when I was trying to start knemo (which turned out wasn't installed), and it kept selecting a song in Amarok. The second time, I started entering systemsettings, saw it guessing what I wanted to do, and pressed right arrow. I couldn't get it to crash again like that.

The crash does not seem to be reproducible.

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