Comment 2 Kevin Fenzi 2009-03-02 04:59:03 UTC 
I am seeing this same crash here as well.
Comment 3 Matthias Clasen 2009-03-02 05:26:39 UTC 
        inhibit->priv->proxy_session = dbus_g_proxy_new_for_name_owner (connection,
                                                                        GPM_SESSION_MANAGER_SERVICE, GPM_SESSION_MANAGER_PATH,
                                                                        GPM_SESSION_MANAGER_INTERFACE, NULL);
        if (inhibit->priv->proxy_session == NULL) {
                egg_warning ("failed to get proxy: %s", error->message);
                g_error_free (error);
                return;
        }

Obviously, if you want to print the error message, you should pass &error to the dbus_g_proxy_new_for_name_owner call...
