Having some trouble with Rhythmbox 12.5-0ubuntu2 and Karmic (12.6.31-13-generic). When I go to Edit -> Plugins and try and start the DAAP sharing plugin I get an error saying "Could not activate DAAP Music Sharing". I have simplifymedia installed but both Rhythmbox and DAAP sharing worked fine in Jaunty and only broke when updating to Karmic. Here is some debugging info:
