To summarize: The issue happens if you run su <command> gksu <command> because it doesn't clear the environment. If you use su -l <command> (or su - <command>) gksu -l <command> you get a login-like session with the environment reset. So, if you insist on using su or gksu to run X/GNOME applications (which is imho not a good idea), I would suggest that you use it only in combination with "-l". -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
