Hello,
This is now more difficult as you can't reproduce this Kyle but on my 
side this is consistent.
With kdbus I can get no access to apps running as root while without 
kdbus the access works like a charm.
I am running Arch linux linux 4.1.4-1, gnome 3.16, orca master, 
at-spi2-core 2.16 or at-spi2-core master (i've tried with both), 
at-spi2-atk 2.16 or at-spi2-atk master (i've tried with both).
I am attaching a journalctl output coresponding with both attempts with 
dbus and with kdbus. When trying with kdbus more messages are printed to 
the log hopefully suggesting something.

I have tried doing this with my account and with a fresh user account to 
avoid possible configuration issues.

If this does not appear to be a bug, can anyone suggest me on how to fix 
it at least on my system?

Greetings

Peter
