Accessible events stop being emitted after exploring menu

[Joanmarie]

Steps to reproduce:

1. Enable Orca
2. Up/Down Arrow amongst users
3. Press F10
4. Up/Down Arrow in the resulting menu
5. Press Escape
6. Up/Down Arrow amongst users

Expected results: Orca would present the users in steps 2 and 6

Actual results: Orca fails to present the users in steps 6

Reason why: Accessible events stop being emitted so Orca is never told that focus/selection changes. If Orca doesn't know about it, Orca cannot present it.

I am attaching a quick and dirty, Orca-free tester to reproduce the problem. Instructions are in the file. I will attach the output and explanation next.

As you will see in the attached log file (created by using the previously-attached tester and performing the steps in the opening report):

1. Up and Down initially result in accessible events:

>>> KEY PRESSED: Up
<<< KEY RELEASED: Up
object:state-changed:focused(1, 0, 0)
 source: [password text | Enter password for Joanmarie Diggs]
 host_application: [application | unity-greeter]
>>> KEY PRESSED: Down
<<< KEY RELEASED: Down
object:state-changed:focused(1, 0, 0)
 source: [push button | Login as Guest Session]
 host_application: [application | unity-greeter]
>>> KEY PRESSED: Up
<<< KEY RELEASED: Up
object:state-changed:focused(1, 0, 0)
 source: [password text | Enter password for Joanmarie Diggs]
 host_application: [application | unity-greeter]

2. But after arrowing within the menu that results from pressing F10 and then pressing Escape, events go AWOL:

>>> KEY PRESSED: Escape
object:state-changed:iconified(0, 0, 0)
 source: [window | ]
 host_application: [application | unity-greeter]
window:deactivate(0, 0, Login Screen)
 source: [frame | Login Screen]
 host_application: [application | unity-greeter]
<<< KEY RELEASED: Escape
>>> KEY PRESSED: Down
<<< KEY RELEASED: Down
>>> KEY PRESSED: Up
<<< KEY RELEASED: Up
>>> KEY PRESSED: Down
<<< KEY RELEASED: Down
>>> KEY PRESSED: Up
<<< KEY RELEASED: Up
>>> KEY PRESSED: Down
<<< KEY RELEASED: Down
>>> KEY PRESSED: Up
<<< KEY RELEASED: Up
>>> KEY PRESSED: Up
<<< KEY RELEASED: Up
>>> KEY PRESSED: Down
<<< KEY RELEASED: Down

Hy,

I now installed with unity-greeter 0.2.7-0ubuntu1 package version, and if I see right, the indicators works right.
If I opened indicator menues, move some menu items and press ESCAPE key, the issue is not happening. Perhaps developers doed a fix with affecting this bug with other packages?
I looked this with unity-greeter --test-mode command resulted screen and normal login screen.
I using my Ubuntu 12.04 system with latest master Orca version, and enabled the proposed updates.
Can you experienced similar right results?
