Bug 224946

Application: amarok (2.2.2)
KDE Platform Version: 4.3.95 (KDE 4.3.95 (KDE 4.4 RC2))
Qt Version: 4.6.0
Operating System: Linux 2.6.32-12-generic x86_64
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
While listening to a randomized playlist, I cleared it out and went to construct another.  While in the "Local" file browser Amarok hard-crashed with the option to restart.  I did and it crashed again before I could select any music.  I shut the crash report out, and restarted manually and the same thing happened- unable to select/ listen to music.  I did not notice whether Amarok was searching for cover art.

The crash can be reproduced every time.

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