Python 3.10.7 Docs fails with Sphinx 5.3.0

[marxin]

Noticed that here:
https://build.opensuse.org/package/live_build_log/openSUSE:Factory:Staging:L/python310:doc/standard/x86_64

[   32s] + /usr/bin/make -O -j8 V=1 VERBOSE=1 -j1 html

The problematic line:
395 label = translators['sphinx'].gettext(label)

If I print the content of translators I get:

{('console', 'sphinx'): <gettext.NullTranslations object at 0x7ffff7664eb0>, ('general', 'sphinx'): <gettext.NullTranslations object at 0x7ffff6113cd0>, ('general', 'sphinxcontrib.applehelp'): <gettext.NullTranslations object at 0x7ffff5620910>, ('console', 'sphinxcontrib.applehelp'): <gettext.NullTranslations object at 0x7ffff56209d0>, ('general', 'sphinxcontrib.devhelp'): <gettext.NullTranslations object at 0x7ffff5622d40>, ('console', 'sphinxcontrib.devhelp'): <gettext.NullTranslations object at 0x7ffff5623e20>, ('general', 'sphinxcontrib.htmlhelp'): <gettext.NullTranslations object at 0x7ffff5623f10>, ('console', 'sphinxcontrib.htmlhelp'): <gettext.NullTranslations object at 0x7ffff5623f40>, ('general', 'sphinxcontrib.serializinghtml'): <gettext.NullTranslations object at 0x7ffff564ceb0>, ('console', 'sphinxcontrib.serializinghtml'): <gettext.NullTranslations object at 0x7ffff564cf10>, ('general', 'sphinxcontrib.qthelp'): <gettext.NullTranslations object at 0x7ffff564cfa0>, ('console', 'sphinxcontrib.qthelp'): <gettext.NullTranslations object at 0x7ffff564d630>, ('general', 'about'): <gettext.NullTranslations object at 0x7ffff56a2830>, ('general', 'bugs'): <gettext.NullTranslations object at 0x7ffff56a3790>, ('general', 'c-api'): <gettext.NullTranslations object at 0x7ffff536a800>}

This issue is also observed in the python-docs-zh-tw's CI jobs for building the translated Python 3.11 doc. Here is the sample GitHub Action log.

sphinx.locale.translators is originally a defaultdict(gettext.NullTranslations) but changed to a dict in this commit. Modify pyspecific.py's translators['sphinx'] (3 occurrences) to translators[('general', 'sphinx')] should probably solve the issue?

Great you found the commit which caused that. Can you please create a pull request that will make the change?

I believe sphinx.locale._ could be used to the same effect, which is backwards compatible.
