listview problem with 1.2.1 that worked just fine with 1.2.0

Hello,

I have a very simple code that works fine with 1.2.0, but it fails under 1.2.1 with

Uncaught TypeError: Cannot read property 'options' of undefined

Sample Code:

<ul>
    <li>
        <p>My Custom List Item</p>
        <ul data-role="listview">
            <li>JQM List View Item</li>
        </ul>
    </li>
</ul>
