Error message: Uncaught TypeError: Cannot read property 'top' of null
Find on http://www.virgilio.it/.
Example for reproducing:

<body>
<script>
	var counter = 0;
	var getHtml = function () {
		return '<div>Hello ' + (counter++) + '</div>';
	};
	
	var loadHandler = function (iframe) {
		var win = iframe.contentWindow;
		var doc = iframe.contentDocument;
		
		win.__renderer__ || (win.__renderer__ = true, setTimeout(function () {
			doc.open();
			doc.write(getHtml());
			win.__renderer__ = true;
			doc.close();
		}, 0));
	}
	
	var div = document.createElement('div');
	
	div.innerHTML = '<iframe src="javascript:\'\';" onload="eval(\'(\' + loadHandler' +
					'.toString() + \')(this);\')"></iframe>';
	
	var iframe = div.firstChild;
