Why is this HTML causing the page to go blank

I'm using jQuery to do a $.get request.

$.get(url, {}, function (result) {
        $('#FactsheetTabs .tab_container div:visible').fadeOut(100, function () {
            $('#FactsheetTabs .tab_container')
            .html(result)
            .fadeIn(100);
});

The response object contains (among other stuff) the following HTML:

<img 
    id="VB_2wCo_bvai" 
    name="VB_2wCo_bvai" 
    width="570" height="243" 
    style="border:0;" 
    usemap="#imVB_2wCo_bvai" 
    src="http://ie-sv-corda72:2001/?@_CPRVB_2wCo_bvai" /> 
    // this URL is to an image on one of our internal servers

The problem is that with Firefox or Chrome (as I can see in Firebug's Net tab), after the .html(result) function executes, the browser starts a brand new reqeust to get the image.. and this just results in a blank page showing up in the browser, rather than the new HTML rendering on the screen with the image.

Has anyone seen an issue like this before? Any idea how to resolve this?

Edit: The complete response code is as follows:

Doing a document.write after the page has fully rendered is a bad thing since it will create a new document when you do this. So if any of your document.writeln get executed in that script then that is probably causing your page to be blanked.
