Another alternative means I can't use the GLib bindings in the client to
receive the signals, but this works:
"type='signal', interface='com.burtonini', member='SignalTest', destination='%s'",
dbus_bus_add_match (connection, match, NULL);
I'm still torn over if this is really sick, or a cunning solution.
