[orca-list] Running Orca in a VNC session

[Bill Cox <waywardgeek gmail com>]

I would like to run Orca in a VNC session on a remote computer, and
I'd like to port-forward my local speech-dispatcher port to that
machine so that the remote copy of Orca running in a VNC session can
talk to my local speech-dispatcher.  When I try running Orca in a VNC
session, it exits with the following message:

bill> cat foo
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/pymodules/python2.6/orca/orca.py", line 1747, in main
    init(pyatspi.Registry)
  File "/usr/lib/pymodules/python2.6/orca/orca.py", line 1266, in init
    registry.registerEventListener(_onChildrenChanged,
  File "/usr/lib/python2.6/dist-packages/pyatspi/registry.py", line
331, in __getattribute__
    raise RuntimeError('Could not find or activate registry')
RuntimeError: Could not find or activate registry


Does anyone know what I need to do to get Orca running in a VNC session?

Thanks,
Bill
