Created attachment 70859 [details]
current.xspf

Deleting this .kde/share/apps/amarok/current.xspf fixed the crash.
Comment 3 Myriam Schweingruber 2012-05-06 11:00:16 UTC 
And which Amarok version is this about?
Comment 4 Rex Dieter 2012-05-06 14:40:43 UTC 
2.5.0
Comment 5 Myriam Schweingruber 2012-05-06 22:31:24 UTC 
Thank you for the feedback, this is solved in git already.
