Description neil underwood 2010-08-15 03:14:13 UTC 
Application: amarok (2.3.1)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.33.6-147.2.4.fc13.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
I have gstreamer installed but Amarok still will not play mp3's so I checked the backend.  Xine was selected so I changed it to gstreamer and it crashed.

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

Xine is the recommended backend for Amarok currently, installing the libxine codecs should be enough to be able to play mp3 files.
Comment 2 Martin Sandsmark 2010-08-18 15:04:09 UTC 
fixed in g9485735 (not the most elegant, but should work). Thanks for reporting with full debug symbols!

I have the same problem, but I have no clue what you mean with "fixed in g9485735". Could you please be more specific on how to fix the problem.
Thank you.
Comment 4 Martin Sandsmark 2010-08-19 03:25:58 UTC 
I have committed a patch to the source code of Phonon in Git (g9485735 is a reference to the commit).
You'll have to wait for a new version to be released and your distro to package it, or them to backport it to their existing version.

New crash information added by DrKonqi

amarok (2.3.2) on KDE Platform 4.5.1 (KDE 4.5.1) using Qt 4.7.0

- What I was doing when the application crashed: I was changing backend engine from xine to gstream while Amarok was scanning my collection folder.

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