Comment (by smcv):

 The native factory doesn't implement introspection, so dbus-python has to
 guess what signature you wanted based on the parameters it's given, and
 may (indeed, is likely to) get it wrong.

 Explicitly specifying the signature (as in the attached patch) is a
 reasonable solution, particularly if you have to deal with "awkward"
 services like this which don't support Introspect().
