In string length access plugin "Equal to" option not work

I found that In string length access plugin "Equal to" option not work

In ctools_string_length_ctools_access_settings operator defenition following

  $form['settings']['operator'] = array(
    '#type' => 'radios',
    '#title' => t('Operator'),
    '#options' => array(
......
      '=' => t('Equal to'),
......
    ),
    '#default_value' => $conf['operator'],
  );

but in ctools_string_length_ctools_access_check operator switch following

  switch ($conf['operator']) {
.................
    case '==':
      return $length == $conf['length'];
..............
  }
