Orca Error at session startup

[Bart Bunting <bart ursys com au>]

Hi all,

I'm running the latest Ubuntu feisty and have recently started getting
the following error after i log in.

Asistive technology  support has been requested for this session but
the accessibility registry was not found. Please insure that the
at-spi package is installed.
Your session has been started without assistive technology support.

I'm not sure where this is comeing from, have of course got at-spi
installed, and have even tried reverting the version of at-spi to the
last couple of versions in case this was the issue.

This didn't make any difference.  Does anyone know where this might be
comeing from and how I should go about troubleshooting it?

Regards

Bart
