Is it an activity? Activities shouldn't need it, but you can see how
the DS sets a main loop for dbus-python to use:

All the func calls in that example seem to be sync, and there's no
signals neither. So perhaps what raises that issue is
I can imagine how that setting may require a loop, but in your case I
think you can drop it.
