I can duplicate this for gnome-libs 1.0.8 but not with gnome-libs 1.0.15

Red Hat 6.0 doesn't include nethack. It is shipped on "Power Tools" but not
a Gnome version.

Some 6.0 games are setgid "games". I'm not sure it will give a setgid shell on
those because the gnome games wrapper is at least intended to drop privs
before the program does anything. It may do.

Mandrake != Red Hat

not remotely.
