UI Tabs with Facebox in IE7 throw a Exception


Updating my projects to jQuery 1.3...
And now using jQuery 1.3 and UI revision 1636 at SVN
http://jquery-ui.googlecode.com/svn/trunk/ui/
But in IE 7 I get a script error:
Exception thrown and not caught
What that error can be?
In jQuery 1.2.6 and older UI Tab, It's was work fine.
Some body help me?
