Before everything, I ask for to excuses for my poor English.

I am creating new distro and I configured locales correctly. I removed all other and I installed only the Brazilian Portuguese.
I run "dpkg-reconfigure locales". Root is configurated:

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

But, when i create a new user, the language is configured to DE

LANG=pt_BR
LANGUAGE=de
LC_CTYPE="pt_BR"
LC_NUMERIC="pt_BR"
LC_TIME="pt_BR"
LC_COLLATE="pt_BR"
LC_MONETARY="pt_BR"
LC_MESSAGES="pt_BR"
LC_PAPER="pt_BR"
LC_NAME="pt_BR"
LC_ADDRESS="pt_BR"
LC_TELEPHONE="pt_BR"
LC_MEASUREMENT="pt_BR"
LC_IDENTIFICATION="pt_BR"
LC_ALL=pt_BR

Somebody can help me?
Thanks
