in egg_recent_view_gtk_set_model you can read:

        if (view->model != NULL) {
                g_object_unref (view->model);
                g_signal_handler_disconnect (G_OBJECT (model),
                                             view->changed_cb_id);
        }

it should be:

        if (view->model != NULL) {
                if (view->changed_cb_id != 0)
                        g_signal_handler_disconnect (G_OBJECT (view->model),
                                                     view->changed_cb_id);
                g_object_unref (view->model);
        }

that is, you have to disconnect from view->model not from model

right?
