Comment 18 for bug 91229

Sorry, no more ideas from me. I think you've just gotten over my head. I don't know much about kernel stuff. Debugging wise, though, here's what seems to be unrelated to the problem:

Amarok version
Amarok recompilation
Kubuntu version
Libtag recompilation (using newest version)

Kernel related things would seem to be the most likely for me now. I hope you get this figured out, since we get a lot of reports on launchpad about this, but not much action. Keep up the good work!
