Setting iframe body html value in msie

[jf.hovinne]

In msie 6.0, I get an error when I use:

var doc = iframe.contentWindow.document;
$j(doc.body).html(myValue);

The call works fine with previous jQuery versions - the error only appears in current 1.1.1, at line 163 of jquery.js:

this.appendChild( a );

where I get: "Error: invalid argument."

The call works in Mozilla and Opera.
