Ah, thanks for the quick reaction. I'll test your patch tomorrow.

Using QtDBus during global destruction aside, can one use 
QDbusConnection::sessionBus() multiple times or will that create so many 
connections to the session bus? The documentation doesn't seem to make that 
explicit, and your answer above could also apply only to using the method during 
global take-down.
