Describe the Bug

Looks like documentation build fails with exception like below

+ /usr/bin/sphinx-build -n -T -b man docs build/sphinx/man
Running Sphinx v7.1.2

The above exception was the direct cause of the following exception:

Expected Behavior

Documentation build should be OK.

To Reproduce

Just execute for example sphinx-build -n -T -b man docs build/sphinx/man in source tree.
