[jQuery] G is undefined

I get the following error:

G is undefined
init()()jquery-1....2.min.js (line 12)
(?)()()Carousel.aspx (line 30)
I()jquery-1....2.min.js (line 19)
F()()jquery-1....2.min.js (line 19)
[Break on this error] (function(){var l=this,g,y=l.jQuery,p=l.....each
(function(){o.dequeue(this,E)})}});

in jquery-1.3.2.min.js

when I call this method of mine:

$.getJSON("http://localhost:59396/xxx/xxxHandler.ashx?
action=xxxjson",
function(Data) {
$.each(Data.items, function(i, item) {
alert('got here');
carousel.add(i, mycarousel_decodeEntities(item.ImageTag));
if (i == 3) return false;
});
});

I know I can get inside function(Data){ and that the error starts at
$.each I believe
