Another interesting note.
I erased my rhythmbox configuration directory and copied my old one form my Karmic partition and it started right up! :)
rm -rf ~/.local/share/rhythmbox/ cp -a /media/karmic_OLD/.local/share/rhythmbox/ ~/.local/share/
So this my be a viable workaround for others having this problem.
