Gnome doesn't load when orca is installed

[Jan and Bertil Smark Nilsson <jbsn@tpg.com.au>]

Greetings,

After upgrading to 'Sid, orca loads before I've logged into 
Gnome. I can move in the Orca window, But i can't log in. The 
login window is on the screen, but the keystrokes are not passed 
on. All I have on my braille display is the Orca window.

In order to log in to Gnome, I have to remove Orca, restart gdm3 
and re-install orca. and start it manually.

What could be wrong?

Bertil
