Abnormal quit when connecting a bluetooth audio device

[MervynCheng]

I try to connect a bluetooh audio device to mac os(host).
when the device is automatically connected to mac, virtualbox abnormally shutdown the guest os which is xp here.

also, so far the audio input has a problem, which is in ticket 14386.

Probably, these two errors belong to the same root problem.

disire to be fixed asap.

upload the log of this problem.
