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".
