Sortable: toArray function not working

The toArray function in ui.sortable seems to be broken in 1.6b.

Looks to me like the function has been restructured (in rev 472) to use:

this.getItemsAsjQuery(o && o.connected)

but o is not being passed in the function call.

It appears to fix it if you change line 80 from:

toArray: function(attr) {

to:

toArray: function(attr,o) {

(But you'll probably want to check my code!)
