Simple HTML test file, no jquery involved

I made a simplified version of the crash and tested with latest nighlty 51303
on Windows. This time, no jquery involved. Basically, the code that crashes
WebKit is as follows:

<script>
    function openPreferences() {
                setTimeout(function() {
                    document.getElementById('DIV').style.display = 'none';
                }, 100);
            }
        </script>

    <body onmousedown="openPreferences()"> 
        <div>
            <div ID="DIV">
                <div> <img id="IMG" src="5day.png"/> </div>    
            </div>
        </div>
    </body>    

If hiding (or removing) the image from DOM is done on a timer, then the right
click menu can be displayed and in addition to that, when the CopyImage action
is chosen, Webkit crashes since the renderer for the node is 0. 

Regards,
Mihnea
