Two issues:

1) we need a g_type_init() at the start main() as for some reason that's not done elsewhere

2) the testcase exits prematurely inside dbus_shutdown() with status 1, failing the testcase:

#0  __GI__exit (status=status@entry=1) at ../sysdeps/unix/sysv/linux/_exit.c:29
#1  0x000000318e42bb89 in _dbus_exit (code=code@entry=1) at dbus-sysdeps-unix.c:2693

which for the dbus 1.4.10 that I have installed, corresponds to:

      if (connection->exit_on_disconnect)
        {
          CONNECTION_UNLOCK (connection);            
          
          _dbus_verbose ("Exiting on Disconnected signal\n");
----->    _dbus_exit (1);
          _dbus_assert_not_reached ("Call to exit() returned");
        }
