A2DP headset does not appear in sound settings output list.

This is a regression from Oneiric:

Steps:
- Pair Nokia BH-503 stereo BT headset to the laptop.
- Verify headset is connected: Headset LED slow-blinks blue, device appears as connected under BT settings.
- Open sound settings.
- Sources listed: Digital SPDIF out, Analog out(selected).

The connected headset's A2DP and headset profiles no longer appear as outputs/sinks; they both used to, in oneiric and natty before that. I used the A2DP output fairly often without issues.

FWIW, the same headset also works as a A2DP sink on a different Thinkpad that still runs Lucid.
