Description Daniel Hahler 2010-12-15 17:45:41 UTC 
Application: amarok (2.3.90)
KDE Platform Version: 4.5.85 (4.6 Beta2)
Qt Version: 4.7.0
Operating System: Linux 2.6.36.2-blueyed i686
Distribution: Ubuntu 10.10

-- Information about the crash:
I have just reported another, similar crash, but want to report this one again, since it is not being detected as duplicate at least.

See bug 259972 for the related crash.

This time I had changed the backend to VLC, after having it changed to GStreamer before and noticed that it started "playing", but without any output.

-- Backtrace:
Application: Amarok (amarok), signal: Aborted

Comment 1 Myriam Schweingruber 2010-12-15 23:52:27 UTC 
These crashes are both related to Phonon, not to Amarok, please check for duplicates in the phonon bugs list

*** This bug has been marked as a duplicate of bug 259855 ***

New crash information added by DrKonqi

amarok (2.4.3) on KDE Platform 4.7.4 (4.7.4) using Qt 4.7.4

- What I was doing when the application crashed:

After experiencing bug #292297 I proceeded to switch Phonon backend from GStreamer to VLC. When applying the change, Amarok crashed and I received this crash reporter window.
