They're how xterm, Eterm and rxvt all came installed at least. My
guess is so it can write to /var/log/wtmp or /var/run/utmp to keep
track of logins. I don't see that as such a big security hole. A
malicious Eterm might fill up /var, but chances of that on my
machine aren't great.

Odd. Seems to make no difference here. Removing the setgid bit makes
it crash with a different error:

sh: -c: line 1: unexpected EOF while looking for matching `''
sh: -c: line 2: syntax error: unexpected end of file

The line in theme.cfg was "print_pipe 'lp''"
Changed that to "print_pipe 'lpr'"
Same error.

I changed the line to read "print_pipe true" and it no longer
returns an error, but still crashes out, whether it's setgid or not.
I might just disable the PrintScreen key in X. But thank you Tony
and Craig for your ideas! Muchly appreciated. :)

Regards,

Bernard.
