testing/sid: upgrade atspi to version 2.53.1-1 break orca on my system

[Jérémy Prego <jeremy-lists@jeremyp3.fr>]

Hello,

I don't know if this is the right way to report my bug, but I discovered 
that updating the atspi2 stack to version 2.53.1-1 prevents orca from 
starting with a python error :

I'm pasting below the list of packages I have to install for 
accessibility, I hope I haven't forgotten any.

downgrade from "gir1.2-atspi-2.0" to launch orca again
