Cover how to add more than one folder to watch
Submitted by Reuben Thomas
The manual says:
"If you want to add more than one folder to watch, use gconf-editor and add it to the list /app/rhythmbox/library_locations"
Here, "/app" should be "/apps".
Also, it might be useful to explain that Rhythmbox will sometimes add locations itself, e.g. if you have the UbuntuOne Music Store activated. This can otherwise be confusing (because thinking you have only set one location for music, the Preferences dialog still says you have set multiple locations).
