Comment 9 for bug 930785

My Ubuntu12.04 installation has language-selector package v 0.79 and still crashes with the message:
   File "/usr/lib/python2.7/dist-packages/dbus/connection.py", line 651, in call_blocking
     message, timeout)
 DBusException: org.freedesktop.Accounts.Error.Failed: running '/usr/share/language-tools/save-to-pam-env' failed: no output

Typing latin characters in the terminal yelds question marks, na typing 'locale' outputs:
LANG=
LANGUAGE=
LC_CTYPE="POSIX"
LC_NUMERIC="POSIX"
LC_TIME="POSIX"
LC_COLLATE="POSIX"
LC_MONETARY="POSIX"
LC_MESSAGES="POSIX"
LC_PAPER="POSIX"
LC_NAME="POSIX"
LC_ADDRESS="POSIX"
LC_TELEPHONE="POSIX"
LC_MEASUREMENT="POSIX"
LC_IDENTIFICATION="POSIX"
LC_ALL=

My ~/.pam_environment has:
LANGUAGE=en
LANG=en_US.UTF-8
LC_NUMERIC=pt_BR.UTF-8
LC_TIME=pt_BR.UTF-8
LC_MONETARY=pt_BR.UTF-8
LC_PAPER=pt_BR.UTF-8
LC_NAME=pt_BR.UTF-8
LC_ADDRESS=pt_BR.UTF-8
LC_TELEPHONE=pt_BR.UTF-8
LC_MEASUREMENT=pt_BR.UTF-8
LC_IDENTIFICATION=pt_BR.UTF-8

Any other info I can check on my system to help?
