When the directory services list in the configuration dialog gets focus (and the previous focus widget was not a child of the "X.509 Directory Services" group) then NVDA reads "X.509 Directory Services" twice.

This is caused by a quirk in Qt which reports the title of a group box as accessible name for the direct children of the group box (similar to how labels work) unless the children report their own accessible name. In case of the directory services editor the list and the buttons are contained in a plain QWidget which doesn't report its own accessible name so that the group box title is used as last resort.
