I have checked the code and shouild be in these lines:

...
    foreach ($response as $item){
      $itemId=$item['id'];
      unset($item['id']);
      $item['fieldname']=$options['fieldprefix'].':'.$itemId.($item['multi_value'] == 't' ? '[]' : '');
      $item['id']=$options['fieldprefix'].':'.$itemId;
      $item['untranslatedCaption']=$item['caption'];
      $item['caption']=lang::get($item['caption']);
      $item['default'] = self::attributes_get_default($item);
      $item['attributeId'] = $itemId;
      $item['values'] = array();
      if(count($valueResponse) > 0){
        foreach ($valueResponse as $value){
          $attrId = $value[$options['attrtable'].'_id'];
          if($attrId == $itemId && $value['id']) {
            // for multilanguage look ups we get > 1 record for the same attribute.
            $fieldname = $options['fieldprefix'].':'.$itemId.':'.$value['id'];
            $found = false;
            foreach ($item['values'] as $prev)
              if($prev['fieldname'] == $fieldname && $prev['default'] == $value['raw_value'])
                $found = true;
            if(!$found)
              $item['values'][] = array('fieldname' => $options['fieldprefix'].':'.$itemId.':'.$value['id'],
                                'default' => $value['raw_value'], 'caption'=>$value['value']);
            $item['displayValue'] = $value['value']; //bit of a bodge but not using multivalue for this at the moment.
          }
        }
      }
...

How can i solve? i use PHP 5.3
