Dear Maintainer, The message catalog for Norwegian Bokmål is installed in /usr/share/locale/nb_NO/LC_MESSAGES/gajim.mo (or /usr/lib/python3/dist-packages/gajim/data/locale/nb_NO/LC_MESSAGES/gajim.mo in newer versions). This has the effect that for users who set LANGUAGE=nb (per the documentation at https://www.gnu.org/software/gettext/manual/html_node/The-LANGUAGE-variable.html) the message catalog is not found. Norwegian Bokmål is spoken only in Norway (not Sweden, not Denmark); therefore there is no point in storing the message catalog only in /usr/share/locale/nb_NO/ and not under /usr/share/locale/nb/ . The file should be moved to /usr/share/locale/nb/LC_MESSAGES/gajim.mo (or /usr/lib/python3/dist-packages/gajim/data/locale/nb/LC_MESSAGES/gajim.mo in newer versions).
