The example I remember is firestarter starting yelp as root when you view the help menu, which is undesirable, but not a security problem with gksu. When you run an application with root privileges, you are trusting it to operate securely with those privileges. Running yelp as root is a minor violation of that trust, but it's a firestarter bug, not an insecurity in gksu - apps that run as root may also launch other apps as root in the course of their normal operation.
