Comment 2 for bug 442332

It seems banshee became uninstalled in the upgrade from 9.04 to 9.10. Banshee is a suggested package for gnome-do so no dependency problems should have existed. I imagine if I was able to start gnome-do I'd see that the banshee plugin was still selected and this was causing the dependency to be a requirement.

Installing Banshee fixes the problem. Plugins should probably disable themselves if the recommended dependency isn't available.
