translator.gettext infinite recursion

Describe the bug

Hello,
A collegue of mine had a weird bug in an experiment.

During an experiment, the summary HTML gereration by sphinx crashed with an RecursionError.
In the log file, it seems that is a bug in the locale module.

I send you the traceback log file generated by Sphinx.
I saw that is about language catalogs and my collegue didn't had the environment variable LANG set at all.
I try to reproduce the bug with same configurations but for the moment I don't have this crash.

If somehow you know the bug, do you know how I can avoid it ?

Have a good day

We need the content of conf.py and locale/language settings to be able to reproduce this.

About the locale/language settings I didn't touch it
Unfortunately, I'm not authorized to send you the .rst template files

The build is done by the command

from sphinx.cmd.build import main as sphinx_main_build
(...)
sphinx_main_build([str(SPHINX_PATH), str(Path(file).with_suffix(".spx")), "-q")

hi @AA-Turner and the good folk of Sphinx, just to let you folks know we are seeing similar issues, both with sphinx 8.1 and 8.2, and only since a couple days now, see our CircleCI test and the RTD build - to note that during my attempts to fix the issue, with sphinx 8.2, I have seen a couple (but few and far between) cases when docs builds actually succeeded, so it appears to be flaky, with most of runs failing though 🍺

For the while I added the line
`language="en"' in the conf.py file.

I'll only have news of this change in 10 days. (Hollydays)

I hope my thread is not a waste of time for Sphinx teams.
Best regards
Or cheers 🍻
