Either CGI.pm or the CGI plugin is at fault, at least in some
circumstances.  Apparently, running under Apache::Template
is not considered to be running under "mod_perl", so CGI.pm
doesn't set/reset the params from the env-vars.  I have seen
this in production, but have not reduced it to a test case,
so I've not submitted a bug yet.  But if you look at the source
for CGI.pm, you can see that it goes into a special mode for
running from Apache::Registry, but obviously those same
variables are not provided in Apache::Template.

Hmm.  Maybe Apache::Template is at fault, if it's trying to act
like registry for the top-level page?

Anyway... param() and CGI.pm and Apache::Template *do not mix*
in the current setup.  Stay away from them.
