Amarok won't play sound

[Patrick O'Callaghan]

F12 fully uodated, including KDE 4.3.4.

Sound from mplayer, Flash video etc. all works, but Amarok doesn't. In
fact if I play a track the cursor doesn't even advance. The Settings
dialogue hasn't been touched since installation. The Sound Config button
(which just calls the System Settings panel) works, including the Test
button. Sound is configured for PA. The backend is Xine.

The console shows a bunch of "QPainter::begin: Cannot paint on a null
pixmap" messages, if that matters.
