Bug 242622

Application: amarok (2.3-GIT)
KDE Platform Version: 4.4.4 (KDE 4.4.4)
Qt Version: 4.6.3
Operating System: Linux 2.6.31.12-0.2-desktop x86_64
Distribution: "openSUSE 11.2 (x86_64)"

-- Information about the crash:
I manually added several songs from my external harddrive (mounted at /media/Multimedia) to my playlist, these files were NOT in my library. When a song has finished, Amarok crashes instead of playing the next song in the list.

Two scenarios did happen:
1) Amarok was completely shut down and the Crash Reporting Assistant showed up
2) Amarok froze completely (GUI was shown), did not play a next song and did not react on mouse/keyboard/trayicon. Killed the process, and then the Crash Reporting Assistant showed up

The crash can be reproduced every time.

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