Bug#911362: few packages report not able to register with accessibility bus

[Samuel Thibault]

Hello,

Please keep the bug mail address in Cc, so that our findings is
recorded.

I'll have a look at your details (thanks!) later, there is just one
quick question:

I actually wonder what prompts gtk to try and load atk-bridge. From your
troubleshoot run, it seems you have atk-bridge in

echo $GTK_MODULES

But I wonder where it is coming from. AFAIK it's only requested from
/etc/environment.d/90atk-adaptor.conf and
/etc/X11/Xsession.d/90atk-adaptor, which come from libatk-adaptor
itself.

Could you find out (probably in /etc) where this is coming from?

Yes it is :)
