[ubuntu] Rhythmbox not found on gconf-editor

view story

http://ubuntuforums.org – I want to change the music files directory which appears as "Multiple Locations Set" on my Rhythmbox to a set of directories of my choice. But using the UI it only lets me select one. I read using gconf-editor under /apps/rhythmbox I could achieve this, but there's no rythmbox under my /apps on gconf-editor. Has this changed? If not, how can I get it in there? Best regards (Hardware)
