I mostly use Amarok for listening to (dowloaded) talk radio shows; they're so good to fall asleep to at night ;)
Recently Amarok has started not to advance in the playlist, meaning that it plays the first track, and then stops. Sometimes after several hours, it suddenly starts playing the next track, which has given me quite some surprises :D

Reproducible: Always

Steps to Reproduce:
1. Add some tracks to the playlist.
2. Double-click on the first track to start playing.


Actual Results:  
Only the first track plays, then it stops though the tracks seems to be still playing.

Expected Results:  
The playlist should advance to the next track and start playing that one.
