New submission from Denis Laxalde <de...@laxalde.org>:
On my (Debian 10) system, 'pydoc -k' crashes as follows:
$ python3 -m pydoc -k foo
Traceback (most recent call last):
File "/usr/lib/python3.9/runpy.py", line 197, in _run_module_as_main
return _run_code(code, main_globals, None,
File "/usr/lib/python3.9/runpy.py", line 87, in _run_code

ModuleScanner().run(callback, key, onerror=onerror)
File "/usr/lib/python3.9/pydoc.py", line 2248, in run
loader = spec.loader
AttributeError: 'NoneType' object has no attribute 'loader'
(The same happens with current 'main' of CPython.)
The module that is tried to be loaded is 'ansible.galaxy.data', installed in
/usr/lib/python3/dist-packages/ and it uses a custom (Ansible) finder
_AnsiblePathHookFinder.
Maybe this finder has problems, but since Finder.find_module() may return None,
I believe this should be handled by pydoc's ModuleScanner.
If agreed, I'll prepare a fix accordingly.
