NIS V 19.8.0.14 - Accessing URL Causes Norton Toolbar to Crash

I have an application that checks for updates by passing the following URL to the default browser:

 

     http://zabkat.com/chkupd.php?v=2.1.0.2&p=1

 

Since the 19.8.0.14 update, this URL causes the Norton Toolbar (error message says "Norton Confidential") to crash.  This happens even if I enter the URL manually.

 

I've been able to duplicate the problem in IE9, Firefox, and Chrome on multiple PC's.
