With "fallback=True" gettext.translation behaves the same as
gettext.install and uses NullTranslations in case the
translation file for given language was not found (as opposed to
throwing an exception).
Fixes:
# LANG is set to any "unsupported" language, e.g. en_US.UTF-8
$ chcat --help
Traceback (most recent call last):
File "/usr/bin/chcat", line 39, in <module>
t = gettext.translation(PROGNAME,
File "/usr/lib64/python3.9/gettext.py", line 592, in translation
raise FileNotFoundError(ENOENT,
FileNotFoundError: [Errno 2] No translation file found for domain: 'selinux-python'
