Comment 16 for bug 1445520

Ok, setting back to new for the moment.

I don't know what is going on, other than I suspect something is broken on your system, as I have not seen any other reports of broken Orca and accessibility from other upgrades.

You could try to re-install orca and the accessibility stack packages, and then as an alternative, remove them and purge their configurationfiles, and then re-install.

The packages you want to reinstall are gnome-orca, at-spi2-core, libatspi2.0-0, gir1.2-atspi-2.0, libatk-adaptor, libatk-bridge2.0-0, python3-pyatspi.
