  if (isset($parent_lookups[$parent])) {

    // prevent endless recursion in case of malformatted data in database
    return $properties;
  }
  $query = 'SELECT * FROM {themekey_properties} WHERE parent = %d ORDER BY weight';
  $result = db_query($query, $parent);
  while ($item = db_fetch_array($result)) {
