Lucas De Marchi 80bdcca7ed edbus: avoid cyclic unref ... If we are freeing a EDBUS_Connection_Name its name_owner_changed signal handler may hold a pointer and try to unref it when deleting the signal handler. We can't simply make the signal handler hold a reference to the connection name, otherwise edbus_connection_name_gc will never be triggered because of cyclic references. Thus, just set the cn->name_owner_changed->bus to NULL before trying to delete the signal handler.
