Trying introspect with python bindings

AFAIK the python bindings currently only send a DBus signal when you
actually make the call. Eventually they'll probably do introspection
when you get the interface, but that's not happening right now. So
you'll only know if something was invalid once you try.

(I don't think anything really supports introspection right now, fwiw)
