I am getting the same __exposedProps__ error when attempting to iterate over the array returned by GM_listValues().

The following simple script shows the issue:

// ==UserScript==
// @name        Demonstrate __exposedProps__ warning
// @namespace   personal
// @include     SITE_URL
// @require
// @require
// @grant        GM_listValues
// @version     1
// ==/UserScript==

var gmValues = GM_listValues();

gmValues.forEach(function(val, index){

The console shows:

Exposing chrome JS objects to content without __exposedProps__ is insecure and deprecated. See for more information.

draftKeys.forEach(function(val, index){

Additional Details: OSX 10.8.1, Firefox 15.0.1, GreaseMonkey 1.1



Confirmed. Accessing the length property works without logging this, but setting it exposed makes forEach stop logging.
