[Bug 1186530] [NEW] Bluetooth audio devices disconnects

[Saverio Miroddi]

Public bug reported:

My bluetooth audio devices suddently disconnect, regularly, at random
intervals.

It's very annoying, also because sometimes it's possible to reconnect to
them (disconnect -> reconnect, or turning bluetooth off then on), but
sometimes not.

This same bug used to happen with Ubuntu Quantal. I can reproduce it
daily, but I don't see any pattern.
