Application: amarok (2.4.3)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.8.0
Operating System: Linux 2.6.40.4-5.fc15.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
amarok crashes whenever I attempt to queue any mp3 media.  ogg's seem ok.

$ rpm -q amarok phonon-backend-gstreamer
amarok-2.4.3-3.fc15.x86_64
phonon-backend-gstreamer-4.5.90-2.fc15.x86_64

(tried with phonon-backend-gstreamer-4.5.1-1.fc15 with similar results).

This only started happening recently, but I'm not sure yet if some other update is relevant.

The crash can be reproduced every time.

-- Backtrace:
