Description jjunk11 2012-09-12 11:46:02 UTC 
Application: amarok (2.6.0)
KDE Platform Version: 4.8.5 (4.8.5) (Compiled from sources)
Qt Version: 4.8.2
Operating System: Linux 3.4.3-jtd x86_64

-- Information about the crash:
- What I was doing when the application crashed:

I had just finished playing a Podcast from TWiT, and when the next item in the playlist (a local mp3 file) should have played, amarok crashed instead.  Dynamic mode was enabled, and I had manually inserted the podcast into the playlist previously.

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

The problem is with the phonon-backend-gstreamer, you should upgrade to the version 4.6.1 at least, this is already fixed. Current stable and recommended version of the backend is 4.6.2
