If my theory is correct it'll be difficult to patch, unfortunately.

The Device* is passed as signal argument, but I fear the signal gets queued. If
now in another thread the device gets destroyed, we call deleteLater on the
Device and then we get into the crash situation.

The bad news is that this could happen in many areas. The Device* argument is
passed along in quite a few signals. So if my theory is correct, this might be
crashy in various places. The good news is it should be possible to verify in
the DebugConsole.
