[jQuery] Problem with IE7/jQuery's AJAX load function

[fadeslayer]

I experienced a problem with jQUERY's AJAX load function in IE7.

I have a tag cloud on our site which, on click onto a word, loads page
recurrencies of that tag in site's pages. But in IE7, when data from
JSP come back to jquery, I get a runtime error, specifically in line "
if ( value != undefined ) elem[fix[name]] = value; " from the code
snipped below



attr: function(elem, name, value){
                var fix = jQuery.isXMLDoc(elem) ? {} : jQuery.props;

                // Certain attributes only work when accessed via the old DOM 0 
way
                if ( fix[name] ) {
                        if ( value != undefined ) elem[fix[name]] = value;
                        return elem[fix[name]];

                }


Is it a jquery's bug or there is something which interferes with
jquery in my page?

In FF3 it works great
