A possible bug in QT At-spi bridge the tree role handling

Hy,

I experienced an interesting issue with Skype and Qt At-spi related in 
Ubuntu 12.04 when I used 3.4 and master Orca screen reader version. 
Hopefuly I describe right place the following issue:
If I logged in my Skype account, the contact list tree is working right. 
Orca get QT At-spi the real selected contact names.
Unfortunately when my logged out contact friend logged in again in 
Skype, this is not happening. If I moving contacts list in up arrow key 
to search my friend contact name with I would like talking, I not found 
the list.
I see only two "echo/soundtest service" contact name. The first this 
named contact is real the test call contact, but the top of list item is 
not, this contact my logged in friend contact name. I verifyed this with 
following test:
1. With up arrow key select the first "echo/soundtest service" contact 
name, press application button my keyboard, and choose rename menu item. 
The edit box show first the real "echo/sound test service" contact name.
2. Press up arrow to jump the second mistake named new logged in 
contact, and repeat the test. When I press up arrow key, Orca spokened 
me the "echo/soundtest service", this text present my braille display. 
But when I choosed the rename menu item, the edit box right presenting 
my friend real contact name.

If I restarted with Orca Screen Reader, all works right again.
In Ubuntu 12.04 the qt-at-spi 0.2.0-0ubuntu1 packaged version awailable.
I no, Skype is a binary softvare, but possible doing any fix this 
problem related with qt-at-spi bridge?

I reported this issue for Orca in Bugzilla with following report:
