Comment:

 This bug has changed since filosofo's major update was applied:

 Now if you try to make a post/page/whatever a child of itself in a menu
 you encounter a JavaScript error any time you try to load the menus page,
 causing only half of the page to render. Steps:

 * Create a menu[[BR]]
 * Add the same post to menu twice[[BR]]
 * Make post child of itself[[BR]]
 * Click save

 The error which occurs:
 {{{Uncaught TypeError: Object #<an Object> has no method
 'autocomplete'}}}, line 312 of nav-menu.dev.js

 Using console.log(el) before this call I get the quick-search-posttype-
 post input element, this suggests this is the element throwing the error.

 Not had much chance to look into this, busy with exams :-(, but seems like
 there a no checks in place to stop menu elements being children of
 themselves.
