1. Problem Description:

A custom apache config directive defined in a <Location> together with
a PerlResponseHandler makes the request handling crash (apache dumps 
core, see below).
Nothing printed in the error_log nor the access_log.

httpd.conf contains:
--------------------
PerlLoadModule Xi::TestConf

<Location /test>
  XiTest test
  SetHandler modperl
  PerlResponseHandler Xi::Test
</Location>

TestConf.pm:
------------
package Xi::TestConf;

use Apache2::Module ();

my @directives = ( { name         => 'XiTest' } );
Apache2::Module::add(__PACKAGE__, \@directives);

sub XiTest {
     my($self, $parms, $arg) = @_;
     $self->{XiTest} = $arg;
}

1;

Test.pm:
--------
package Xi::Test;

use Apache2::RequestIO ();

use Apache2::Const -compile => qw/OK/;

sub handler {
     my $r = shift;

     $r->print("Hello");

     return Apache::Const::OK;
}

1;
