This is Debian bug <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=264076>

- get a panel with a notification area
- launch rhythmbox and wait for its icon to appear in the NA
- play a song
- remove the NA area from the panel, rhythmbox exits

If you're not playing a song this does not seem to happen.

I get following messages on my terminal when running a rhythmbox prior the crash:

(rhythmbox:12890): GLib-GObject-WARNING **: invalid uninstantiatable type
