How reproducible:

Completely reproducible. Segfaults every time.

Steps to Reproduce:

1. Fresh session, observe sound services working properly using built-in sound hardware.
2. Use gnome bluetooth tools to pair / connect to paired headphones.
3. Sound-related services are gone. Observe segfault message in logs.
  
Actual results:

kernel: [  171.585363] pulseaudio[1888]: segfault at 9000000 ip 42d70ad6 sp bf9ace44 error 4 in libc-2.15.so[42cee000+1a8000]

Expected results:

Beautiful music in my headphones. :)

Additional info:

- Same hardware was working fine in Fedora 16.
- I enabled debug logging in pulseaudio, then I grabbed a log snapshot of the issue. (Attached.)
