Comment 1 Myriam Schweingruber 2014-03-19 00:20:20 UTC 
We would need a way to reproduce this reliably, if it only happens sometimes this is hard to track. Apparently it happens on track change and you are suing a playlist generator or a dynamic playlist, right? Then please provide the XML file for that playlist as well, it is located in $HOME/.kde/share/apps/amarok/

Could you please run Amarok from a konsole with 'amarok -d --nofork' for some time and when it crashes, provide the last 100 lines of the output?
Comment 2 Zach 2014-03-19 14:52:41 UTC 
About my playlists:
I add my entire local collection to the playlist and put it on Random Tracks with Higher Ratings favored.  I have no user created playlists.  

 I'll be running Amarok in debug mode until this happens again.
Comment 3 Myriam Schweingruber 2014-08-10 20:43:30 UTC 
Any news? Apparently it didn't crash in over 4 months...
Comment 4 Myriam Schweingruber 2015-01-23 13:45:39 UTC 
Closing for lack of feedback. Please feel free to reopen this report if you can reproduce this with Amarok 2.8 or later.
