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...
