Description Greg Hudson 2004-03-25 20:29:23 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6)
Gecko/20040207 Firefox/0.8

Description of problem:
If /etc/sysconfig/i18n does not exist and GDM_LANG is not set,
/etc/profile.d/lang.csh leaves LANG undefined. 
/etc/profile.d/less.csh then fails in:

  if ( $?LC_ALL ) then
    setenv LANGVAR $LC_ALL
    setenv LANGVAR $LANG

RH9 did not have this problem.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Remove LANG from the environment
2. Run tcsh

Actual Results:  You see the error message:
  LANG: Undefined variable.
and the user's dotfiles are not evaluated.
Comment 1 Karsten Hopp 2004-03-29 04:23:17 EST
LANG is always set in Red Hat Linux. Lots of applications will break 
if you remove random environment variables. 
Please set LANG to C (setenv LANG C) if you want to have default 
Comment 2 Greg Hudson 2004-03-29 05:32:15 EST
Just as an application should not dump core for lack of an environment
variable, a cshrc fragment should not bomb out for lack of one either.
 Given that it is trivial to fix this bug, correctness alone argues
for a fix rather than an excuse.

(Also, empirically, running without a LANG setting worked fine in RH9,
with the exception of some "man" issues which also applied to LANG=C.
 So it is not true that "lots of applications will break" in this case.)
