Comment 25 for bug 147883

i've found specifically what the problem is and how to fix it in gconf.
When rhythmbox runs for the first time it sets the entry in "gconf > apps >rhythmbox > library locations" to /home/ubuntu/Music, which causes the errors. Instead it should set the value to file:///home/ubuntu/Music (obviously replace ubuntu with the actual user). This then doesnt cause the errors, and works correctly. It is also the value put into gconf when you reselect the "music" folder as the library location, so it shouldnt cause any other side effects.

the problem still exists on the RC live cd btw. I hope this info is useful for getting it fixed before hardy final
