Could you check by running it with a non-English locale listed that
appears in the ‘translations’ directory?

Maybe run the application in ‘strace’ to see whether/where it looks for
its translation files.

Qt has its own mechanism for translation of UI messages.  The
LC_MESSAGES thing is used by the ‘gettext’ function, part of libc.

Applications using ‘gettext’ tell libc the location of their
translations using ‘bindtextdomain’.

Qt must have a way to know where translations are; maybe it has a
function similar to ‘bindtextdomain’, in which case things will just
work regardless of where translations are installed.
