Setting the filter to "greater than now" issues a SQL error

Had a SQL error when using a filter on date GREATER THAN now

It looks like in line

function date_views_filter_handler($op, $filter, $filterinfo, &$query, $field_type = 'iso') {
  include_once(drupal_get_path('module', 'date_api') .'/date.inc');
  $value = $filter['value'];
  $type = $filterinfo['type'];

  // Do some validation of input values before creating any SQL.
  switch ($type) {
    case 'YEAR':
    case 'MONTH':
    case 'DAY':
      if (empty($value) || !($value == 'now' || is_numeric($value))) {
        return;
      }
      break;
    default:
      if ($field_type == 'int' && (empty($value) || !($value == 'now' || date_is_valid($value, DATE_UNIX)))) {
        return;
      }
      elseif (empty($value) || !($value == 'now' || date_is_valid($value, DATE_ISO))) {
        return;
      }
      break;
  }
  $field   = $filterinfo['extra']['field'];
  $column = $filterinfo['extra']['column'];
  $formats = date_get_formats($field);
  $db_info = $filterinfo['content_db_info'];
  $table   = 'node_data_'. $field['field_name'];
  $table_field   = $db_info['columns'][$column]['column'];

$db_info doesn't get any values from $filterinfo array. As a matter of fact, the key "content_db_info" is not present in the $filterinfo array.
