Line 625 is

drupal_set_message(t("Unable to generate a signwriter image. It may be that your font was not found by the freetype library. Do you have GD and Freetype installed? Check the output of phpinfo().", 'error'));

'error' parameter should be in drupal_set_message() and not in t():

drupal_set_message(t("Unable to generate a signwriter image. It may be that your font was not found by the freetype library. Do you have GD and Freetype installed? Check the output of phpinfo()."), 'error');
