i compiled amarok with kde 4.5.0 and had some serious problems myself. unfortunately i have no idea what the problem might be and i won't have time within the next two weeks. i have some code cleanups on my todo list that would remove the engineNewTrackPlaying function anyway. but they won't make it into amarok 2.3.2. so either somebody knows what is going on here or we should disable the labels applet for the next release.
Setting to confirmed. Daniel, please drop by in the developer channel on irc.freenode.net

Rick, did this really fix the problem for you? Because I also added some pointer checks and it would indeed fix the crash but create a freeze in updateLabels() I guess. That's the point where I gave up (for now). And btw. I don't have permissions to edit this bug. Where can I get them?
(In reply to comment #4) > And btw. I don't have permissions to edit this bug. Where can I get them? As already stated earlier, please come to the amarok-dev channel on irc.freenode.net to discuss that.
