Bug 224169

Application that crashed: amarok
Version of the application: 2.2.1
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-17-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
After playing one album I replaced the playlist with another one an double klicked on the first song. Replay started but I wasn't able to select another position at the timeline of this song - but again it was replayed fine. So I double klicked on another song -> amarok crashed instantly.

 -- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
