I guess I meant

g_object_class_install_property (file_chooser_dialog_class,
                                 PROP_FILENAME,
                                 g_param_spec_copy (
                                    g_param_spec_pool_lookup (pspec_pool,
                                              "filename",
                                              GTK_TYPE_FILE_CHOOSER)));

ie use the interface properties just a some kind of templates for
ordinary properties.
