I've seen that error from my own bash scripts when I neglect to
enclose a variable in double-quotes before testing it, as

    if [ $THIS = "That" ]; then

and when in some situation that variable is not set.  I would not
expect to see that error from the line

    if [ "${_LC_SAVE_}" = "null" ]; then

because ${_LC_SAVE_} _is_ surrounded by double-quotes and so the
binary operator = will have operands on both sides.

However, profile_d is sourcing every .sh file in /etc/profile.d and
one or more of those files may not be enclosing some variable(s) in
double-quotes.  All of the .sh files in my /etc/profile.d handle
their variables correctly, so the error is probably in the
/etc/profile.d/<package>.sh file of some package that I don't have
installed.

Regards,
Gary
