Comment 1 Cam Menard 2013-04-27 04:05:10 UTC 
Also: This started crashing immediately following Kubuntu Linux upgrade to 13.04.  Complete removal and installation of Amarok did not fix the problem.
Comment 2 Myriam Schweingruber 2013-04-27 09:34:32 UTC 
The problem is upstream with gstreamer, not much we can do about this, sorry.

As a workaround, please use the phonon-backend-vlc instead.
