Fix Xubuntu Rhymbox error: Unable to activate plugin Jamendo and Unable to activate plugin Magnatune Store
I usually get this error when i install Rhythmbox from an xfce environment.It comes up whenever i start it. although the program would still run. i always find it very annoying. however searching the problem reveals that installing libgnomevfs2-extra from synaptic fixes it. so i guess one less thing to worry about.
