After cleaning ~/kde/share/apps/amarok and setting amarok to use sqlite instead of sql, now I can see my mp collection once again. But if I try to play anything, amarok dies, and this is the backtrace it tries to send via email:

---------------

xine-lib is version 1.1.1, and I've already tried rebuilding it and amarok.
I just noticed (after removing ~/.kde/share/config/amarokrc and ~/.kde/share/apps/amarok) that it will play the .ogg welcome track. It just hangs or dies when I try to play my mp3 collection.

Do you have libmad installed?

Yes, I have libmad, version 0.15.1b
I had amarok 1.3.9 working perfectly. Anyway, I'm rebuilding xine-lib and libmad now. We'll see if it helps.

Still no joy. I get crashes in xine mad plugin if I try to play my mp3 from inside amarok 1.4.0a. But if I play those mp3 in xine, they play perfectly. And, as I said, amarok 1.3.9 played them perfectly.
