This traceback error message producing following simptoms:
For example in l10n.gnome.org translation webpage when I wbrowsing 
prewious translation diffs with Up or Down arrow keys with a project, 
Orca doesn't spokening links, Orca nothing spokening this situation when 
I jump a link with Up or Down arrow key. When I reviewing screen 
contents with a braille display, the  braille display presented the 
links. Very interesting, if I moving Up or Down arrow key this links, 
braille display is not refreshing automaticaly, but only this type links 
not happening this tasks, perhaps because not processed the input events 
when this traceback is happening.

Possible fix this error with 3.1.1 master branch and 3.0 branch?
Unfortunately I not remember what bugreport are reported prewious this 
traceback error message.
I tested this issue now with Ubuntu Natty, and Orca 3.1.1 master version 
with Firefox 4.0, but this issue are reproducable with Orca 3.0.0 and 
Firefox 3.6 too.

Have a chance to fix this issue before next Orca 3.0 maintenance version 
is coming out?

Attila
