Description wikispam 2014-12-19 17:07:56 UTC 
When I have not used Amarok for an extensive period (say: 8 hours or more) and then click on a track in the playlist and click the play button -- or sometimes just by clicking the track -- Amarok just crashes. Has been happening for many months now.

Reproducible: Sometimes
