The problem is here: components/com_jce/editor/extensions/links/joomlalinks/menu.php line#240 [ approx, its in _types() ]

if (is_object($query)) {
//---------> FIX joomla 2.5 there is no client_id in #__menu_types table...so no menus appear
$version = new JVersion();
if($version->isCompatible('3.0')){
$query->select('*')->from('#__menu_types')->where('client_id = 0')->order('title');
} else {
$query->select('*')->from('#__menu_types')->order('title');
}
} else {
$query = 'SELECT * FROM #__menu_types ORDER By title';
}
