what do you mean by 'Start emacs from woody box, displayed on unstable box' ?

do you log into the woody box with ssh?
When you using ssh-3.8p1, lease try the following:

(quoted from Bug#236936, Colin Watson)
Starting with 3.8, you need to set ForwardX11Trusted if you want to
affect other X clients. From ssh_config(5):

     ForwardX11Trusted
             If the this option is set to ``yes'' then remote X11
             clients will have full access to the original X11 dis-
             play.  If this option is set to ``no'' then remote X11
             clients will be considered untrusted and prevented from
             stealing or tampering with data belonging to trusted X11
             clients.

             The default is ``no''.
