FCKeditor settings - error highlights wrong field

On admin/settings/fckeditor/editg (Edit Global Profile), if I make a mistake entering data in the "Force simplified toolbar on the following fields" field ('simple_incl_fields'), it gives me an error message, but highlights the wrong field.

To fix, in fckeditor.module, change line 500 from:
$errors['excl_fields'] = t("Invalid field specified: %1", array("%1" => $field));
to:
$errors['simple_incl_fields'] = t("Invalid field specified: %1", array("%1" => $field));
