Like I replied earlier, you were exactly correct:
  http://svn.haxx.se/users/archive-2005-03/1460.shtml

You had a patch that you applied to Apache
  http://svn.haxx.se/users/archive-2005-03/1452.shtml
  
I went ahead and wrote a very simple mod_perl2 handler that does much
the same thing. It simply changes the scheme of the Destination header
from https to http. For anyone who is interested here it is:

package ProxyDav;

use strict;

use Apache::RequestRec ();
use APR::Table ();
use URI;

use Apache::Const -compile => qw(OK);

sub handler {
        my $r = shift;

  my $method = $r->method();
        if ($method eq 'MOVE' || $method eq 'COPY') {
          my $destination = $r->headers_in()->get('Destination');
                my $new_destination = URI->new($destination);
                $new_destination->scheme('http');
                $r->headers_in()->set('Destination', $new_destination);
        }
  return Apache::OK;
}

1;

__END__
