Sentry Crash Report:

Description Bernhard Jungk 2013-11-06 20:26:55 UTC 
Application: amarok (2.8.0)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-13-generic x86_64
Distribution: Ubuntu 13.10

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

I have two soundcards (internal Intel and SB Extigy connected via USB). When I woke up my laptop after a suspend to disk, amarok crashed. I think that the devices are not directly available again after resuming and thus the alsa/phonon configuration changes, possibly several times.

-- Backtrace:
Application: Amarok (amarok), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

The bug is upstream in gstreamer directly. Not much we can do about this, as support for the new gstreamer 1.x is not yet available for phonon, but it is work in progress.
