Reference to a not initialized variable in flag_weights_set_flag()

In flag_weights_set_flag it says $handlers instead of $handler when calling flag_weights_set_weight ( $handlers->content_type). Can't see anywhere else where $handlers is used; if this is related to how the module is used, then close this but I can't imagine how that ever worked.

In related (aka how I noticed the typo) popped out this function to flag/weight using an existing flag. (The flag using content type never worked for me btw, don't currently really see the purpose of it).

function flag_weights_set_flag_with_flag($flag_name, $content_id, $account = NULL, $weight = 0) {
  $handler =  flag_get_flag($flag_name) ;
  $ok = $handler->flag('flag', $content_id, $account);
  if ($ok && $weight != 0) {
    if (!isset($account)) {
      $account = $GLOBALS['user'];
    }
    flag_weights_set_weight($handler->fid, $handler->content_type, $content_id, $account->uid, $weight);
  }
  return $ok;
}
