[orca-list] when good fixes go bad (AKA the list hang in Firefox)

[Joanmarie Diggs <joanmarie diggs gmail com>]

Hey guys.

In order to fix the problem of us no longer being able to arrow to push 
buttons in Firefox, I checked in what seemed like a good and innocent 
fix.  All it does is turn checks on obj.text into checks on obj.text and 
obj.text.characterCount.  In other words, don't assume that just because 
an object claims to have text means that it actually has text.  Somehow 
this is responsible for the reported (un)ordered list hangs.  Sorry!!!

Today I have to head into Boston for a meeting.  I'll bring the laptop 
on the commute.  And if I don't work it out during the commute, I'll 
work it out tonight.  In the meantime, my recommendation is to not check 
out the very latest from svn.  If you want the very latest, then reverse 
the patch attached to bug 470332.

Again, my most sincere apologies and stay tuned for the fix!
