Deploy t function in cmf_get_roles function of cmf.module.

When I translate CMF filter page, I found the thing I can not translate which are roles directly from roles table.
Should the t function be deployed in cmf_get_roles function? See the code below.
Thanks much for such a great module in advance.

/**
 * Builds a list of available roles
 *
 * @param the format in which to return the list
 * @return array of all available roles
 */
function cmf_get_roles($op) {
  switch ($op) {
    case 'names':
      $result = db_query('SELECT rid, name FROM {role} ORDER BY name');
      break;
  }
  $roles = array();
  while ($role = db_fetch_object($result)) {
    //$roles[$role->rid] = $role->name; // It should consider multi-lingual by using t function.
    $roles[$role->rid] = t($role->name);
  }

  return $roles;
}
