Comment 24 for bug 1672166

I am sorry for inconvenience I give rise to.
I use standard Ubuntu 16.04 repositories.

And I found below processes in running applications:

dbus-daemon --config-file=/etc/at-spi2/accessibility.conf --nofork --print-address 3
at-spi-bus-launcher --launch-immediately
at-spi2-registryd --use-gnome-session

I found `Accessibility Profile Manager Indicator` in startup applications and I tried with both disabled and enabled but nothing changed.
