can't do "screen" as normal user
I'm having some problems with my Debian server since I updated today.
When logged in as normal user, I can't do screen anymore:
When switching to root, everything works fine:
Must be connected to a terminal.
not a tty
"su"ing back to a normal user simply reveals the same problem.

v:~# ll /dev/pts
crw--w---- 1 root tty 136, 13 Nov 17 19:19 13
crw--w---- 1 root tty 136, 21 Nov 17 20:07 21
crw------- 1 web tty 136, 6 Nov 17 20:10 6
v:~# ll $(which screen)
-rwxr-sr-x 1 root utmp 364088 Jul 29 2009 /usr/bin/screen
I tried to search for people with the same problem, but did not really find anything except a 10 year old mailing list that claimed clib6 was faulty at that time.
I checked the apt log for today's update, but there was no libc6 in there.
Since I don't really know that much about terminals with Linux I have no idea what else to try. Anyone got an idea?
