Description Arjon 2011-01-22 20:15:22 UTC

Application: amarok (2.4.0)
KDE Platform Version: 4.5.5 (KDE 4.5.5) "release 1"
Qt Version: 4.6.3
Operating System: Linux 2.6.34.7-0.7-desktop x86_64

-- Information about the crash:
Amarok crashes when backend is changed while amarok is open. It will crash when playback is continued. It works both for changing to xine and changing to gstreamer. Amarok has to be opend (but not playing?) while the change is made

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

reassigning to the new bugzilla product for better bug tracing of the various backends. Sorry for the noise.
