[Bug 838078] [NEW] bluetoothd crashed leaving traces in syslog

Public bug reported:
No idea what caused this or why it happened, but bluetoothd crashed
over-night, leaving traces in syslog. Bluetooth was not recoverable at
this point, forcing me to reboot to get bluetooth running again. The
system in question is an Alienware M15x.
Also, I noticed that 'hcitool dev' at least still shows the adapter, I
just can't do anything with it. And because this just happened at
night, when the machine was sitting idle, I have no idea how to manually
reproduce this either.
Here's a trace from syslog:
