Had the same problem on 8.04. The solution to remove the lucid ppa and purge the ubuntu one music plugin and rhythmbox, followed by a reinstall of both through the standard ubuntu repo seems to have worked.
Not sure whats wrong with the ppa, but someone should fix it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/623655 Title: Error prevents enabling store plugin -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
