[MP2] : REDIRECT_ERROR_NOTES not set on errordocument redirect

[Mark]

-------------8<---------- Start Bug Report ------------8<----------
1. Problem Description:
$ENV{REDIRECT_ERROR_NOTES} not working with MP2
Using latest everything (modperl 2 RC5).
To illustrate, I simply configure Apache with an errordocument:
   ErrorDocument 500 /cgi/printenv
I have a perl-scripts configured like this:
  <Directory "/usr/local/apache2/perl">
    Options ExecCGI
    SetHandler perl-script
    PerlResponseHandler ModPerl::Registry
    PerlOptions +ParseHeaders
  </Directory>
And a script the generates an error:
  #/usr/bin/perl
  barf();
The errordocument 'printenv' output shows REDIRECT_ERROR_NOTES empty.
When the identical barf script is run under CGI (script-alias), 
REDIRECT_ERROR_NOTES
has an error message.
I fooled around with more complex examples, accessing ARP table 
'error-notes' and
that is also empty.

2. Used Components and their Configuration:
