Comment 0 for bug 1511259

In file session-child.c in function session_child_run() variable `locale_var_names` contains explicit list of locale environment variables to inherit. This list lacks of some LC_* variables: LC_PAPER, LC_NAME, LC_ADDRESS, LC_TELEPHONE, LC_MEASUREMENT and LC_IDENTIFICATION. As a result, these variables are not inherited by child session. Therefore, processes inside desktop session set these variables to the value of LANG, instead of appropriate values configured in /etc/locale.conf.

$ more /etc/locale.conf
LANG=en_US.UTF-8
LC_CTYPE=pl_PL.UTF-8
LC_NUMERIC=pl_PL.UTF-8
LC_TIME=pl_PL.UTF-8
LC_COLLATE=pl_PL.UTF-8
LC_MONETARY=pl_PL.UTF-8
LC_MESSAGES=en_US.UTF-8
LC_PAPER=pl_PL.UTF-8
LC_NAME=pl_PL.UTF-8
LC_ADDRESS=pl_PL.UTF-8
LC_TELEPHONE=pl_PL.UTF-8
LC_MEASUREMENT=pl_PL.UTF-8
LC_IDENTIFICATION=pl_PL.UTF-8
LC_ALL=

Inside desktop session:

$ locale
LANG=en_US.utf8
LC_CTYPE=pl_PL.UTF-8
LC_NUMERIC=pl_PL.UTF-8
LC_TIME=pl_PL.UTF-8
LC_COLLATE=pl_PL.UTF-8
LC_MONETARY=pl_PL.UTF-8
LC_MESSAGES=en_US.UTF-8
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=

Notice wrong values of LC_PAPER, LC_NAME, LC_ADDRESS, LC_TELEPHONE, LC_MEASUREMENT and LC_IDENTIFICATION (en_US.utf8 instead pl_PL.UTF-8).

Fix:

Add LC_PAPER, LC_NAME, LC_ADDRESS, LC_TELEPHONE, LC_MEASUREMENT and LC_IDENTIFICATION to the `locale_var_names` array in file session-child.c.
