title: iOS 6 javascript intermittent issues with object.defineProperty
body: <p>Has anyone else noticed intermittent errors/issues in the new iOS 6 javascript engine when accessing properties on objects where the property was defined using newer Object.defineProperty syntax?</p>

  <p>I'm seeing occasions where the javascript will fail stating undefined is not a function on methods of objects accessied as properties on objects defined in this manner.</p>
