export commands ignored in /etc/apache2/envvars script -

Maybe this belongs to Serverfault or launchpad.net, but here we go anyway:

In Oneiric, there is an export command in this script /etc/apache2/envvars , setting LANG. This gets ignored on my server. Any idea why?

I had two more commands in Script /etc/apache2/envvars

export SYBASE=/opt/sybase  
export SYBASE_OCS=OCS-15_0

but they get ignored as well as the output from the printenv.cgi script shows.

Is this a bug or a security feature in Oneiric?

Note that the answer from Sep 27 2011 at 17:29 to this question explicitly says that admins should add export commands to /etc/apache2/envvars .

I found this: A quote from the Oneiric changelog regarding Package sbox-dtc

- Removed the use of Apache envvars which aren't safe (easy to hack).
