jQuery Uncaught TypeError: Cannot call method 'apply' of undefined
===

I'm getting the error on the title. See the screenshot at http://i46.tinypic.com/2drgpio.png

The error is not always there, sometimes I refresh and get no error.

I already put all the code inside $(document).ready(function(){} just in case was something with the DOM not being ready.

The only relevant information is base.js:2371, this is what I see at that line:

    2371: $('.Setlist_In_Action_Button, .SetList_Demo_Link').live('click',function(){
    2372:	$.fancybox({
    2373:		href: this.href,
    2374:	    overlayOpacity: 0.2,
    2375:		centerOnScroll: true,
    2376:		scrolling: false,
    2377:		hideOnOverlayClick : false
    2378:	});
    2379:		
    2380:	return false;
    2381: });

Any ideas what's happening? The error happens on Chrome. I haven't tested other browsers.

Any help is really appreciated.
Thanks!
