For some time, I see the following in my logs: 2025-05-04T09:05:17.154471+02:00 twentytwo gpg-agent[52465]: Loading the "qt_" catalog failed for locale QLocale(English, Latin, United States) 2025-05-04T09:05:17.155039+02:00 twentytwo gpg-agent[52465]: Loading the "qt_" catalog failed for locale QLocale(German, Latin, Germany) 2025-05-04T09:05:17.155059+02:00 twentytwo gpg-agent[52465]: Loading the "qtbase_" catalog failed for locale QLocale(German, Latin, Germany) I've not seen any unexpected behaviour of gpg-agent, maybe this simply skips translations? If this is harmless, then plese consider adding a logcheck rule to mask it out from logging.
