I upgraded, and this seems to point the way to the culprit:
after undoing the out-commented Esperanto-settings in /usr/share/X11/locale/compose.dir and locale.dir and
sudo dpkg-reconfigure locales

1. It seems one (debian?) wishes to do away with the officially merely reserved XX (or EO) and stay with eo; which would be fine.
2. One (E-ists) should inform, that ISO-8859-3 can be dropped in favour of UTF-8, which can be combined more easily with other languages on the system.
