Comment 2 Mark Kretschmann 2009-03-23 08:35:33 UTC 
I'm sorry, but from this backtrace it's not clearly visible to me what line exactly caused the crash (probably dereferening a 0-KSharedPtr).

Also, the code has changed so much in SVN, that this is probably fixed by now (I can't reproduce it here). I did also look a the code from 2.0.2, but could not see an obvious problem there.


I'm going to close this report, but if anyone can get a more precise backtrace for it, feel free to reopen. Here are some tips:

Comment 3 Dan 2009-03-23 12:34:21 UTC 
I launched amarok with command line 
Here is the message in a console after crash :
amarok(6918) CurrentTrack::dataUpdated: CurrentTrack::dataUpdated
ASSERT: "d" in file /usr/include/ksharedptr.h, line 120
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = amarok path = <unknown> pid = 6918
sock_file=/home/daniel/.kde4/socket-localhost/kdeinit4__0

I hope this will be useful ...
Comment 4 Dan Meltzer 2009-03-23 16:25:53 UTC 
This is fixed in trunk.  the line in question is     
m_currentTrack->finishedPlaying( 1.0 ); // If we reach aboutToFinish, the track is done as far as we are concerned.

I don't expect we will do another 2.0 release, so it doesn't really make sense to backport it.  It's related to the fadeout stuff I think.
