Comment 13 for bug 623655

OK, your question told me what I needed to know. I was using the webupd8team ppa for lucid, which apparently outran the support libraries with the latest ubuntu one plugin. I disabled the ppa, uninstalled rhythmbox and all its plugins, then reinstalled from the basic lucid repositories. Everything works now, but I'm sure that I lost some functionality, especially with the plugins, but I do have the ubuntu one music store back.

I'm better now. Thank you for your help tonight.
