from firefox. There are other similar. I have not got this problem
on any other machine. How can I fix it, and ensure it does not happen
again?
I'm not sure, but try running locate on your locale e.g.:
$ locate en_US.UTF-8
/usr/share/X11/locale/en_US.UTF-8
/usr/share/X11/locale/en_US.UTF-8/Compose
/usr/share/X11/locale/en_US.UTF-8/XI18N_OBJS
/usr/share/X11/locale/en_US.UTF-8/XLC_LOCALE
/usr/share/doc/libx11-dev/i18n/compose/en_US.UTF-8.html
If you don't have those (or similar) locale files, you need to enable
and generate that (evidently required, based on your environment)
locale.
Good luck,
