GM_registerMenuCommand is not working in 1.1

[mjh563]

Firefox 16 beta + Greasemonkey 1.1:

The "User script commands" menu doesn't open and gives this error:

Error: TypeError: el is undefined
Source File: resource://greasemonkey/util/emptyEl.js
Line: 4

This basic script will reproduce the problem:

// ==UserScript==
// @name Test
// @grant GM_registerMenuCommand
// ==/UserScript==

GM_registerMenuCommand ("test", function(){alert ("test")});

It works okay in 1.0 but fails in 1.1

Having the same problem with all of my scripts as well.
