Binary package hint: banshee
From a fresh Ubuntu install, open gnome-control-center and click Preferred Applications. Switch to the Multimedia tab. Rhythmbox which is not even installed is set as the default app; this should be changed to Banshee.
/desktop/gnome/applications/media/exec needs to be changed to banshee-1
