manager/qubesmanager/main.py
Marek Marczykowski e0a15c12d4 Replace dbus-python with QtDBus 
dbus-python seems to be not thread safe. After "881ee76 Merge qclipd
into qubes-manager" this occasionally triggers SEGV.
QtDBus seems to be somehow less robust:
 - doesn't automatically convert methods arguments to proper types based
 on introspection data
 - property access isn't working so must call
 org.freedesktop.DBus.Properties methods manually

But besides those problems seems to work stable.
