 The function wp_get_nav_menu_items fails when a "Page" type post has been
 added to a menu.

 This is a fresh install of Wordpress 3.5, using the "Sample Page" page
 added to a menu called "main_menu". This menu has no other menu options
 added to it. This bug also occurs in earlier versions of Wordpress.

 Sample PHP Code:
 {{{
 <?php

 $menu_name = 'main_menu';

 $nav_menu_object = wp_get_nav_menu_object($menu_name);

 $menu_id = $nav_menu_object->term_id;

 $menu_items = wp_get_nav_menu_items($menu_id); <<--- Error occurs here

 ?>
 }}}


 The following error occurs:
 {{{
 Fatal error: Call to a member function get_page_permastruct() on a non-
 object in C:\xampp\htdocs\lchs4\wp-includes\link-template.php on line 271
 }}}

 This occurs in the following area of code:
 {{{
 function _get_page_link( $post = false, $leavename = false, $sample =
 false ) {
         global $wp_rewrite;

         $post = get_post( $post );

         $draft_or_pending = in_array( $post->post_status, array( 'draft',
 'pending', 'auto-draft' ) );

         $link = $wp_rewrite->get_page_permastruct(); <--- happens here
 }}}
 Essentially, the variable $wp_rewrite shows as <Uninitialized> when viewed
 in xdebug using Eclipse.
