Using "trigger('mouseup')" to stop dragging returns "this.helper is null"

If you try this code:

function mouseUp()
    if($('#tomove').offset().left > 400)

        axis:   'x',
        drag: function(event, ui) 

As soon as you reach the 400 px you will get an error, at least in FF 3.6 and IE8, like this one:

this.helper is null

Is this a bug?

Triggering a mouseup event without the necessary event properties causes an error. Don't see an issue there - please use the forum to get help on whatever you're actually trying to do.
