(Hrm, I'm obviously late ;-))

Does this mean that the registryd will start and stay if the value of
at-spi-corba is true, but the value of accessibility is false?

I see that this is implemented with a gconftool-2 call in
pyatspi-corba.pth. As you point out, this is a big hack :-) My main
worry here is that every time python is started, this is called. It's
probably not that much of an issue if this is happening from within a
GNOME session, but I wouldn't want scripts run by sysadmins to have
this, for example.

I can't think of a much better hack right now, but this is probobably
something we should investigate...
