Conflict with popups

When using http://drupal.org/project/popups if viewscarrousel is used on the maincontent (inot in the popup) it generate an exception.
Modifiing viewscarousel.js correct the problem:
(function($) {
Drupal.behaviors.viewscarousel = function(context) {
if (!Drupal.settings.viewscarousel) return;
$.each(Drupal.settings.viewscarousel, function(id) {
if (this.scroll) this.scroll = parseInt(this.scroll);
if (this.start) this.start = parseInt(this.start);
if (this.visible) this.visible = parseInt(this.visible);
if (this.auto) this.auto = parseInt(this.auto);
$('#' + id).jcarousel(this);
});
}
})(jQuery)
