I cannot really help you, as I would need a greater knowledge of
python's dbus interface and avahi's interfaces than I possess in order
to do so. When using gio's C interface for dbus, I have never had to
futz around with different main loops - the default program main loop
(the one which gtk+ uses) is automatically used for gio's asynchronous
continuations unless you go out of your way to set up something
different using g_main_context_push_thread_default(). I am also highly
suspicious of the use of two main loops, which amongst other things
requires a thread for each main loop, but maybe this is an avahi
thing. It begs the question of how the two main loops communicate with
each other, and why.
In addition it looks as if your python library wraps dbus-glib rather
than gio's dbus implementation and I do not know what options that
gives you for main loops, as I don't use it.
