Bug 274052

Application: amarok (2.4.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
I was attempting to queue media from a home media server.  Amarok refused to play queued tracks and crashed when I attempted to play the next track on the queud playlist.

I tried to view the playlist.

The crash can be reproduced some of the time.

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