Would be useful to know which of the strings in append_mount is NULL.
If it is the uuid, I've just fixed this.

new downstream comment describes how to trigger the bug:

"1) insert CD into CD-ROM drive.
2) run ``sudo powertop''
3) after a while, at least on my laptop which is an HP Pavilion DV2815NR, powertop tells you to not let HAL poll the CD-ROM drive.
4) then eject the CD-ROM and re-insert it.
5) the open Rhythmbox."

I can confirm, that those  instructions do trigger the bug for me

Actually, the above instructions  only worked once for me, they weren't consistent.  In my playing around, I discovered a MUCH more consistent bug and I posted here: http://bugzilla.gnome.org/show_bug.cgi?id=550076

It might be related

Well Matthias, seems as if it's fixed by now :) At least Ubuntu doesn't get new dups and don't, too. I'd say to close it in a few weeks unless anybody raises an issue.
