Hmm, works on the command line...

  $ ll /dev/pty0
  crw--w---- 1 corinna vinschen 136, 0 Apr 12 16:28 /dev/pty0
  $ chmod 600 !$
  chmod 600 /dev/pty0
  $ ll /dev/pty0
  crw------- 1 corinna vinschen 136, 0 Apr 12 16:28 /dev/pty0

...but I can easily reproduce it from sshd.  I'll have a look this week.
