[K12OSN] Stopping ctrl - alt - backspace

[Daniel Hedblom]

Hello!

How do i stop the clients from doing ctrl - alt - backspace ? 

I have found that many of them do that and thus i think they bypass the
postsession script that kills their processes. GDM doesnt catch this and gconf-2
and other processes is left in limbo.

Cheers!
