Bug 296454

Application: kmix (4)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: I had just finished doing a dist-upgrade to KDE 4.8.1 and restarted. I began playing a song in Amarok, and it played fine. After the song finished, I clicked the next song in the play list when it crashed. In the time that I began typing up this report, Amarok continued playing the songs in the playlist w/o sound, then automatically the sound came back...

-- Backtrace:
Application: KMix (kmix), signal: Segmentation fault
