Yes, I tested rhythmbox with MP3s under Gutsy. As I recall I did install the codecs after the first attempt told me I was missing them; since sound is completely non-functional I really don't recall now. However, I tested Hardy with the .ogg files in the samples folder, so that shouldn't be a problem.
I have no idea what the rhythmbox errors mean, either, but for something CRITICAL they seemed to have remarkably little impact.
