Rhythmbox only starts once from indicator

[Sam_]

After login Rhythmbox initially can be launched once via indicator.
Close window via window button or via menu music -> quit.
Attempt to launch Rhythmbox via indicator fails. (video)
When finally reaching the buttons it doesn't play anything.

## Initially launching Rhythmbox via dash works fine. But crashes on second and third attempt. bug 926342
ii rhythmbox 2.95-0ubuntu2

## Behaviour is as expected with Oneiric.

Installed daily current of 5th feb. on another pc and it does neither crash nor vanish with:
ii indicator-sound 0.8.0.0-0ubuntu3

Need testing on laptop tomorrow.

[Sam_ (and-sam)]

No luck. Rhythmbox initially opens fine, after closing it never opens again via indicator during a session.
