Good to know! Although, hrm, wouldn't gnome-mag and gok still need it?

Hrm, what about first checking if we're running in a X session? This is
still a hack, but it at least removes the gconftool-2 call in many cases
where we wouldn't want this to happen.

Something like:

import commands, os, sys; os.environ.has_key('DISPLAY') and (commands.getoutput('gconftool-2 --get /desktop/gnome/interface/at-spi-corba') == 'true') and sys.path.insert(0, '@prefix@/lib/python PYTHON_VERSION@/site-packages/pyatspi-corba')

I'm sure some python heroes could find a non-hacky solution ;-)
