rhythmbox doesn't play at all and freezes

Binary package hint: rhythmbox

I have a fresh install of dapper rc.

When I try to play a song in rhytmbox (i have tried both ogg and mp3) it never starts playing, and if I change song it hard freezes. I have an almost empty music library (I only added one album) so that shouldn't be the problem.

Output from rhytmbox -d when clicking on the first song (which is an ogg-file):
[0x8123890] [info_available_cb] rb-shell-player.c:2281 (00:49:55): info: 0
[0x8123890] [info_available_cb] rb-shell-player.c:2300 (00:49:55): Got info_available but entry isn't an iradio station
[0x8123890] [info_available_cb] rb-shell-player.c:2281 (00:49:55): info: 20
[0x8123890] [info_available_cb] rb-shell-player.c:2300 (00:49:55): Got info_available but entry isn't an iradio station

after that some "saving the playlists" messages are printed so it hasn't hung yet. When changing song it just says:

[0x8123890] [rb_shell_player_open_location] rb-shell-player.c:888 (00:51:22): Opening file:///depot/cd collection/Christy Moore/The Christy Moore Collection 81-91/07 - Delirium Tremens.ogg...

And then freezes. Clicking on the "x" gives me a dialog telling me that it rhytmbox is unresponsive.

Since dapper is about to be released really soon I hope you can fix this. If you need more information I will try to provide you with whatever you need as quickly as possible.
