 > It's worth mentioning that this old version of gettext suffers from a
 bug that causes the wrong language to be displayed for users with more
 than one preferred language set in Language & Region prefs. My Bash is in
 French because of it! Looking forward to this update.

 Ah, so THAT'S why I've got so many GNOME apps launching in Japanese for
