[orca-list] update on the recent FF3 list woes/hang

[Joanmarie Diggs <joanmarie diggs gmail com>]

Hey folks.

It seems that the aforementioned "innocent" fix I had made to cause push 
buttons in Firefox to be arrow-to-able exposed a Mozilla bug.  Effective 
the 4th August build, (un)ordered lists are claiming to have a 
characterCount of 0 characters.  If you get suspicious and ask for the 
text anyway, the first character is missing.  The former is at the root 
of the Orca hang reported by Javier.  The latter is the cause of the 
behavior reported by Jan this morning.  Thanks to both of you!

So....

1. I just checked in a defensive patch both to svn trunk and the 
gnome-2-20 branch which should detect the bogus characterCount for lists 
and prevent Orca from hanging when you encounter a list.  If you were 
having the list hanging problem, please grab the latest Orca, re-test, 
and let us know.  Thanks *very* much in advance!

2. If you would like to have your lists spoken in their entirety, I'd 
recommend getting the Firefox trunk build from 3rd August (2007080308).

3. If you would like to track the progress of the Mozilla list bug, it

Take care.
