Yaikes.  Hmmm, this would almost seem like X server trouble.  Gdm doesn't
treat the keyboard and the terminal separately.  Though I wonder if perhaps
some bug in the XDMCP code may trigger this, but I'm unsure how this would
happen.  It would seem to me that if the XDMCP code messed up connections
you'd just get no connection at all rather then two messed up ones.  It would
seem like the incoming and the outgoing connection are swapped.

Are you using just direct xdmcp queries or is there a chooser setup involved?
