Even the minimal module using hotkeys, e.g., the one consisting only of the following lib/main.js throws on console tracebacks:

"use strict";
var url = require("url");
var Hotkey = require("hotkeys");

function goUp() {
    var url = url.URL(require("window-utils").activeWindow.location.href);
    console.log("current URL is " + url);
}

var showHotKey = Hotkey({
  combo: "alt-pageup",
  onPress: function() {
    console.log("Pressed Alt+PgUp");
    goUp();
  }
});

The couple of such tracebacks is (and one runtime error on the top, but that's another issue):

I wrote a fix for this and submitted it as a pull request. 
https://github.com/mozilla/addon-sdk/pull/145
Matej thanks for the bug report!

hwiechers thanks for the fix. I have reviewed code and while overall it's looks good, I had few comments (see pull request) that needs to be addressed before we pull that in.

Just to confirm, that with this pull request applied, I don't get any nonsensical error messages on the console.

Thanks a lot

Myk can you please authorize this change for landing. It's pretty important as otherwise hotkeys API generates error messages in console.
Yup, good point, a=myk for commission during freeze.
