Drop down brings up error 404

Hi,

when using this code:

<select name=\"page-dropdown\"
 onchange='document.location.href=this.options[this.selectedIndex].value;'>
 <option value=\"\">
<?php echo attribute_escape(__('Select Language')); ?></option>
 <?php
  $pages = get_pages('child of=27');
  foreach ($pages as $pagg) {
      $option = '<option value=\"'.get_page_link($pagg->ID).'\">';
    $option .= $pagg->post_title;
    $option .= '</option>';
    echo $option;
  }
 ?>
</select>

My drop down list no longer works in 2.7. It worked fine in 2.6.5.

It still lists the child pages but brings up a 404 messge when trying to retrieve the page and I can see no reason why.

Help is appreciated.
