$ locale
LANG=eo.utf8
LANGUAGE=eo:nl
LC_CTYPE="eo.utf8"
LC_NUMERIC="eo.utf8"
LC_TIME="eo.utf8"
LC_COLLATE="eo.utf8"
LC_MONETARY="eo.utf8"
LC_MESSAGES="eo.utf8"
LC_PAPER="eo.utf8"
LC_NAME="eo.utf8"
LC_ADDRESS="eo.utf8"
LC_TELEPHONE="eo.utf8"
LC_MEASUREMENT="eo.utf8"
LC_IDENTIFICATION="eo.utf8"
LC_ALL=

But it aborts also with a Dutch locale and a C locale.

LANG=
LANGUAGE=
LC_CTYPE="en_US.utf8"
LC_NUMERIC="en_US.utf8"
LC_TIME="en_US.utf8"
LC_COLLATE="en_US.utf8"
LC_MONETARY="en_US.utf8"
LC_MESSAGES="en_US.utf8"
LC_PAPER="en_US.utf8"
LC_NAME="en_US.utf8"
LC_ADDRESS="en_US.utf8"
LC_TELEPHONE="en_US.utf8"
LC_MEASUREMENT="en_US.utf8"
LC_IDENTIFICATION="en_US.utf8"
LC_ALL=en_US.utf8
