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.
