YUI Loader - Combo Bug

Code:
<script src="http://yui.yahooapis.com/3.1.0pr1/build/yui/yui-min.js"></script>
<script>
YUI({combine:true}).use('console','node',function(Y){
  var url = Y.Node.one('link[id]').getAttribute('href'),
      con = new Y.Console();
  con.render();
  YUI.log(url);
});
</script>
Fixed Code in loader.js
   //fixed combo bug
   if(url.slice(-3) ==='.js' || url.slice(-4) === '.css'){
       url += '&';
   }

   url += frag;

   /*
   if (i < (len - 1)) {
       url += '&';
   }
   */
