This might already be fixed in current git, could you maybe try to compile from source?
Comment 2 Myriam Schweingruber 2010-08-26 10:50:12 UTC 
Yes, it was fixed yesterday, see bug 246756

Comment 3 Wonko 2010-08-26 11:08:52 UTC 
I can confirm it is fixed. Sorry for the duplicate, I was pretty sure that it only happened after the last track, not when I manually stopped playback. But apparently I only had paused playback.
