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?
