Thank you for the report.  I can recreate this using client side
commands by using this in a project directory:

  LANG=de_DE.UTF-8 cvs -qn up

These messages came from the sv_membersh perl script set as every user
shell when users ssh into the system.  That script is the access
control script.

That was a problem because the default sshd configuration in the stock
vendor package is "AcceptEnv LANG LC_*" which allowed your LANG to be
passed through.  Since every language locale has not been generated on
the server the perl script generated the errors.  (Perl has been a
watchdog for locale setting problems over the years due to this.)

I have disabled that setting.  LANG is no longer passed through.  This
seems to have resolved this problem.

Thank you again for reporting this problem!
