Dialog Box, Chaos Tools and javascript issues with BeautyTips

I'm using the dialog box module to display the comment form in a jquery dialog.

If javascript aggregation is on, the save buttons are not displayed in the dialog form.

If found out, that BeatuyTips generates a javascript error because ChaosTools loads the aggregated Javascript via AJAX for displaying the dialog form.

In the this function
Drupal.behaviors.beautytips = function() {}

there is the error jQuery.bt is not defined, because it's only a AJAX page load and not the whole page. The jquery plugin is missing and also not necessary.

I added a check in the function and the dialog box works now as expected:

Drupal.behaviors.beautytips = function() {
  
  //Fix Dialog Box
  if(typeof(jQuery.bt) == 'undefined' && jQuery.bt == null){
    return;
  }
  
  jQuery.bt.options.closeWhenOthersOpen = true;
  beautytips = Drupal.settings.beautytips;

Maybe someone can save some debugging hours.. :-)
