You are catching an error, but what is it?

I'm not going to do anything about the PDF patch.  Please create
an new issue in the MapServer Bugzilla and attach the patch to
that issue.  Then the PDF output format maintainer can address it
properly.

At any rate, this thread is decomposing.  Started out about templates
and is now PDF?  To continue the discussion I think we should start
over.
