You need to call gtk_run_dialog() again.  Try something like this:

	done = FALSE;
	while (!done) {
		switch (gtk_dialog_run(dialog)) {
		case GTK_RESPONSE_OK:
			if (data valid) {
				/* do whatever */
				done = TRUE;
			} else {
				/* complain */
			}
			break;

		case GTK_RESPONSE_CANCEL:
		case GTK_RESPONSE_DELETE_EVENT:
			/* do whatever */
			done = TRUE;
			break;
		}
	}

Better yet, dont make the OK button sensitive until the user has entered
something into the filename field.
