Upon upgrading to 13.10, rhythmbox kept crashing on startup, so I updated to rhythmbox 3.0 and that fixed the problem. Now, though, in the sound panel in the top right of the screen I can't control rhythmbox. Clicking the play button will start up rhythmbox as it always has, but I can't skip, pause, or play songs. I tried editing the settings with dconf -editor, but it still isn't working. What can I do to get it working again?
