    This is easily reproducable.

    ssh -X from machine A to B with normal IPv4
      execute "xterm" display appears nicely.

    ssh -X from machine A to B-6 with ssh started "sshd -6"
      Connection is made, output from "-v -v -v" looks normal (to me)
      $DISPLAY is set
      execute "xterm" display fails with an error on opening $DISPLAY
