It does, unless you specifically ask it not to. Does navit reply correctly
to the Introspect() method?

(If not, then the best dbus-python can possibly do is to guess, from the
arguments you've given it, what types the method is meant to receive -
if its guesses are wrong then you'll have to either work around that
deficiency in navit, or get it fixed.)

Like so:

    navit.SomeMethod("callback", dbus.ObjectPath(my_o_object, variant_level=1))

Or, override the introspected/guessed signature with what you know it to be,
and dbus-python will do the right thing:

    navit.SomeMethod("callback", my_o_object, signature='sv')
