Comment 48 for bug 893091

I'd recommend using GDBus for D-Bus in Python 3 code. dbus-python does not follow the principle of "In the face of ambiguity, refuse the temptation to guess", and can't be changed to not do so without seriously breaking compatibility.

Moving from Python 2 to Python 3 seems as good a time as any to switch...

Redesigning dbus-python to make the type system explicit would basically end up with something resembling GDBus (but implemented on top of a less tractable library with worse thread-safety), and nobody's actively working on it anyway.
