the issue should be fixed in that version:

gnome-bluetooth (3.2.0-0ubuntu2) oneiric-proposed; urgency=low

  * debian/patches/lp805311_disconnect-signals-from-adapters-and-devices.patch,
    debian/patches/lp805311_do-not-leak-proxies-for-interfaces.patch:
    disconnect signals for adapters and devices, and also avoid leaking DBus
    proxies for interfaces. (LP: #805311)
