[jQuery] Interface v1.2 Error with jQuery v1.2.1

[moltar]

Hi,

I am using the latest jQuery v1.2.1 and the latest available Interface
v1.2. Here is the sample code that I have broken down to:

$(document).ready(function(){
        $('a.slide').click(function() {
                $('#box').SlideOutLeft('normal');
        });
});

Firebug goes bananas when the event is fired and keeps looping over
the same error, producing thousands of error messages. The error
message reads: "this.options.curAnim has no properties".

Here is the ZIP archive with test files: http://www.mediafire.com/?9eha1idjyyx
