By this you say Thunderbird to use not the LANG setting from your user session and use the system default, this is normally English. The solution for this Lightning problem is written at least once in this report, you probably have installed thunderbird-l10n-$(your_lang) but not lightning-l10n-$(your_lang). If you use Lightning and have installed some l10n package for Thunderbird itself you also need to install the belonging l10n package for Lightning. -- Regards Carsten Schoenert
