Debug.out file with show this problem why happening

Dear Developers,

I tryed latest Oneiric daily live CD with a customized build, I using GNOME fallback session.
When I lot of time activating the desktop, Orca doesn't spokening the desktop icon names, with braille the selected icon name is displaying the braille display.

I maked a debug.out file, and see following interesting traceback error message:

In Orca preferences I enabled the tutorial messages, and basic braille support. If I uncheck the speak tutorial messages check box, the problem doesn't happening.

Reproducation steps:
1. In Orca preferences/speech page check the speak tutorial messages check box.
2. In braille page, check the enable braille support check box, and not change other settings.
3. Go to the desktop, and try move desktop icons. You will be not hear selected desktop icon name. If you try doing where am I operation, Orca will not spokening icon related informations.

I attached the debug.out file.
