[Moo] Adding #undefined to location

[trobrock]

I have some code that is working fine aside from the fact that after
executing it adds a #undefined to the end of the current url, this
isn't a huge issue except that it requires the user to press the back
button twice to go back.  The code with problems is:

var fxReveal = new Fx.Reveal(this.doms.AddNewCardDiv);
fxReveal.reveal().chain(
    function() {
        this.effects.smoothScroll.toElement(this.doms.AddNewCardDiv);
    }.bind(this)
);

I have a problem with the line:
 this.effects.smoothScroll.toElement(this.doms.AddNewCardDiv);

this.effect.smoothScroll is:
this.effects.smoothScroll = new Fx.SmoothScroll({
    wheelstops : false
});
