Since 2019-12-25, around the time we bumped to Sphinx 2.3.1, I see this error in the logs:

@cocoatomo I still see this issue, can someone take a look?

@jfbu might handle this issue, i think.
Anyway, examination of this issue needs information of environment, used tools and reproducing process.

I can reproduce it easily with a clone of docsbuild-scripts by running:

$ mkdir -p www logs build_root
$ python3 -m venv build_root/venv/
$ build_root/venv/bin/python -m pip install -r requirements.txt
$ python3 ./build_docs.py --build-root build_root --www-root www --log-directory logs --group $(id -g) --skip-cache-invalidation --language ja --branch 3.8

it clones what's needed, creates the appropriate symlink, and build, you should get:

ERROR:Command failed (see /home/mdk/clones/python/docsbuild-scripts/logs/cpython-ja-3.8.log at 2020-05-23 15:25:12.651117)

and the log file should contain the full exception:

$ grep -c Improper logs/cpython-ja-3.8.log

We're still having the issue on docs.python.org.
