If screen reader are enabled during login screen, some time Orca exiting

[Attila Hammer]

Dear Developers,

If in Unity Greeter the screen reader a11y support are enabled, random time Orca exiting after started.
This situation Orca spokening following type message:
"Welcome to Orca.
Login frame.
Good bye."
If this problem are happening, I need press two time the CTRL+S keystroke to start Orca again in login screen.

In unity-greeter source package the src/menubar.vala file have following code with Orca related:
    private void screen_reader_toggled_cb (Gtk.CheckMenuItem item)
    {
        /* FIXME: The below would be sufficient if gnome-session were running
         * to notice and run a screen reader in /etc/xdg/autostart... But
         * since we're not running gnome-session, we hardcode orca here.
        /*var settings = new Settings ("org.gnome.desktop.a11y.applications");*/
        /*settings.set_boolean ("screen-reader-enabled", item.active);*/

        UGSettings.set_boolean (UGSettings.KEY_SCREEN_READER, item.active);

        /* Hardcoded orca: */
        try
        {
            if (item.active)
                Process.spawn_command_line_async ("orca --replace --no-setup --disable splash-window,main-window");
            else
                Process.spawn_command_line_async ("orca --quit");
        }
        catch (Error e)
        {
            warning ("Failed to run Orca: %s", e.message);
        }
    }

Hy,

I try run unity-greeter --test-mode command.
I attaching full output the command.
The interesting is following error message:
** (process:8878): WARNING **: unity-greeter.vala:802: Error starting
the at-spi registry: Failed to execute child process
"/usr/lib/at-spi2-core/at-spi-bus-launcher" (No such file or directory)
Real this file doesn't exist for example an Ubuntu 12.04 32 bit system.
The real path this file is following:
/usr/lib/i386-linux-gnu/at-spi2-core/at-spi-bus-launcher

Hopefuly this debug file help little determining why happening this problem.
