[vtkusers] connection to ":0.0" refused by server

[Tom G. Smith (Smitty)]

Hello vtkusers at public.kitware.com,

I got past the initial error (GLX missing, see attached (BTW the
responses from vtkusers were underwhelming :-)) by upgrading to Exceed
3D 7.1, but now when I do -

  export TCLLIBPATH=/contrib/vtk/VTK/Wrapping/Tcl
  vtk /contrib/vtk/VTK/Examples/Modelling/Tcl/hello.tcl

I get the "Hello" graphic, and I can interact with it (rotate, zoom, etc.).
But I also get this error:

  Xlib: connection to ":0.0" refused by server
  Xlib: No protocol specified

and when I press "q" to quit, I get a segmentation fault.  I'm running
this remotely via ssh, and my $DISPLAY is set to -

  bash-2.05a$ echo $DISPLAY
  myhost:11.0

I have no trouble running other X Clients (xterm, xclock, xeyes, MATAB, etc.)
so I don't believe it's my X Configuration causing this.
