Thanks Tim, that is a very interesting log file.

Reading the log file, we at least have one bug in Orca itself (a Python
"NameError").  I am not entirely sure whether this bug triggers the
"hung" process or the "hung" process triggers the "NameError".

I am reassigning this bug to gnome-orca for now, so the maintainer of
orca can have a look at it.

@Orca maintainers: The Orca log shows:

"""
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/orca/generator.py", line 234, in
generate
    result = eval(formatting, globalsDict)
  File "<string>", line 1, in <module>
NameError: name 'ancestors' is not defined

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/orca/generator.py", line 245, in
generate
    globalsDict[arg] = self._methodsDict[arg](obj, **args)
  File "/usr/lib/python3/dist-packages/orca/braille_generator.py", line

    and not self._script.utilities.isLayoutOnly(parent):

1203, in isLayoutOnly
    elif obj.childCount == 1 and obj.name and obj.name == firstChild.name:
