[PyQt] How to process QDBusPendingCallWatcher results?

[Evade Flow]

I noticed that, too, and was a little surprised it worked anyway. But
shouldn't it be:

    @QtCore.pyqtSlot(QtDBus.QDBusPendingCallWatcher)
    def callFinishedSlot(self, call):

When I remove it completely, I get:

    TypeError: callFinishedSlot() takes exactly 2 arguments (1 given)
