Application: krunner (0.1)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.5.0-18-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
I experienced maybe the same crash and marked my report as a possible duplicate.

- What I was doing when the application crashed:
I was searching for "booka" in krunner. While listing the results, I was trying to select one song from the result list and add it to Amarok by the small icon next to the song name in the result list.
It doesn't crash every time, but sometimes.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Oberfläche zur Ausführung von Befehlen (krunner), signal: Segmentation fault
