use effect throws unlimited errors

I have downloaded the newest version of jQuery (1.4.4) and jQuery UI (1.8.7) and I've got enormous count of this same error:

setting a property that has only a getter:

e):f.css(e)}};c.fn.extend({position:fu...ent||t.body;a&&!Ia.test(a.nodeName)&&

jquery....min.js (row 164)

when I've got jQuery 1.4.2 and jQueryUI 1.8.6 I didn't have such an error...

It's happen when this code is evaluated:

$('#trash img').droppable({
		over: function() {
			$obj = $('#trash img');
			$obj.effect('fade', {}, 10);
		}
});
