Bug 233564

Application: amarok (2.3.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-19-generic x86_64
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
Reproducible multiple times. Things to note: network unstable at time of crashes (some packetloss). Full scan worked earlier and continued to work when the network started fully transporting all packets again.

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