Could it be that you have upgraded mod_perl from an ealierer version to
1.24_01 ?

Yes, it should for example the following request to Apache::Status
http://localhost/perl-status/HTML::Embperl::DOC::_5::ISA/ARRAY?data_dump
gives:
Data Dump of HTML::Embperl::DOC::_2::ISA ARRAY
@HTML::Embperl::DOC::_2::ISA = (
'HTML::Embperl::Req'
);
It even easier to click on "ISA Tree" an the start page, there you should
see something like
HTML::Embperl::DOC::_2
HTML::Embperl::Req
HTML::Embperl::DOC::_3
HTML::Embperl::DOC::_2
HTML::Embperl::Req
HTML::Embperl::DOC::_4
HTML::Embperl::Req
HTML::Embperl::DOC::_5
HTML::Embperl::DOC::_4
HTML::Embperl::Req
Could you both checkout if you see these ISA Tree or not ?

Of couse very strange. If it starts when you use Apache::Registry, could you
try to make a minimal Apache::Registry script, say
print "Hello world\n" ;
Does this also trigger the error ?
