[Zope-Perl] constant item trapped by operation mask at ..., while editing perl-scripts

[Andreas Mueller]

       hello !

as mentioned from someone else on the list, I still have problems 
editing perl-script withinin zope. 

my system:

linux-2.2
zope-2.5.1 [source build]
perl-5.6.1 
pyperl-1.0.1
Python-2.1.3

what I do:

- restart zope

- use the menue to add 'script (perl)':
id:		perltest
title:		perltest
arguments:	self
code:
----------------------------------------------------
my $context = shift;
my @res;

for ($context->objectValues(['Folder'])){
	push(@res, join(": ",$_->getId(), $_));
}
join("\n", @res, "done");
-----------------------------------------------------

- use the 'add'-button to add the script.

- test the script by calling 
  http://...../perltest
  output: [<Folder instance at 89e1150>, <Folder instance at 89e1030>, <Folder instance at 89e10a8>]
  [that seems to work]

- but then, when I try to edit the script, and I do not change anything at all, just push the
  'edit'-button, I get the following error messages:
-----------------------------------------------------------------------------------------------------
                          Zope Error

                          Zope has encountered an error while publishing

----------------------------------------------------------------------------------------------------

what's happening here, and how can I solve this problem ?
