Gnome settings hangs orca

[Sam Hartman <hartmans@debian.org>]

On buster , if in a gnome xorg session, I

* use ctrl-alt-tab to get to the top bar

* hit shift-tab to get to the system menu

* arrow down to the bottom

* arrow left to settings

* hit enter

Orca announces the settings frame, but fails to interact with it.  Lots
of CPU gets consumed and the system generally hangs until I hit alt-f4
to close the settings frame.


I'd be interested in any advice on how to debug and isolate what's going
on so I can get something concrete enough to file a bug report.
