DBus GObject & g_object_unref

[Marc-André Lureau]

Given a gobject service:
  dbus_g_connection_register_g_object (bus, "/SomeObject", G_OBJECT (obj));

This gobject could release the service he provides, this way:
g_object_unref (obj);
  and dbus_g_proxy_call (bus_proxy, "ReleaseName", &error,
              G_TYPE_STRING, "org.designfu.SampleService",
              G_TYPE_INVALID,
              G_TYPE_UINT, &request_name_result,
              G_TYPE_INVALID))

I would like to have a proxy notified when the gobject service has released
the service, or
has been destroyed.
  proxy = dbus_g_proxy_new_for_name_owner (bus, "org.designfu.SampleService",

                       "/SomeObject", "org.designfu.SampleInterface",
&error);
either with a weak ref:
  g_object_weak_ref (proxy, (GWeakNotify)_proxy_destroy, NULL);
or a distroy signal (I use the "name_owner" proxy):
  g_signal_connect(proxy, "destroy",
           G_CALLBACK(_proxy_destroy), proxy);

Unfortunately, the proxy destroy signal is emited only when the process
where the service-object is living is terminated (killed or exited).

I think it's related to a "1:xxx" id still on the bus after the unref...

I hope you will understand what I am talking about,  I am sorry to have a so
poor english and not a deep understanding of dbus...

Thanks,
