Enabling undoc-members in v3.2.0 triggers KeyError: 'Shiboken'

[altendky]

Describe the bug

With undoc-members and v3.2.0 I get an exception. I do not get an exception with v3.1.2. Per my local bisecting it was introduced specifically in 88b2ec6.

Exception occurred:
  File "/home/altendky/.pyenv/versions/3.8.3/lib/python3.8/typing.py", line 1223, in get_type_hints
    base_globals = sys.modules[base.__module__].__dict__
KeyError: 'Shiboken'

In case you aren't familiar, Shiboken2 is the wrapper generator used by PySide2 to wrap the C++ Qt library. Shiboken filled that role for PySide. I am using PySide2. I'm not sure if the lack of the 2 is relevant or not.

Note: switching to 'e0d526808a924c95d4c6191070ca21ab9ddab54c'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at e0d5268 add newsfragments/146.doc.rst

Expected behavior
No exception. Though sure, I have not dug into this and an error message from Sphinx may be the appropriate substitute for the raw exception.

[tk0miya]

I think this is same as #8084. Could you try Sphinx-3.2.1, please?

[altendky]

Ha, I literally just noticed 3.2.1 and started running against it right before seeing your note. And yes, that does address the exception. Thank you. That's what I get for checking against the tag I knew about rather than just latest 3.x or such...

[tk0miya]

Good to know. Enjoy documentation!
