I have dialog created like this

1. 
   
2. $('#add_error').click(function(e) {
3.         $('<div>')
4.             .load('/someaction/format/html/')
5.             .dialog({
6.                 title: 'Some title',
7.                 modal: true,
8.                 width: 385,
9.                 close: function() {
10.                      $(this).remove();
11.                 }
12.             });
13. 
    
14.         e.preventDefault();
15.     });

It works ok, but every third (not really sure if its really third) time I click link to open dialog, it fails with error in firebug

"$("").addClass("ui-widget-overlay") is undefined"

In dialog.js that is piece of code:

1. 
   
2. var $el = (this.oldInstances.length ? this.oldInstances.splice(0, 1)[0] : $('<div></div>').addClass('ui-widget-overlay'))
3. .appendTo(document.body)
4. .css({
5. width: this.width(),
6. height: this.height()
7. });

under create: function(dialog) method.
