I unfortunately can't figure out how to replicate this yet.  It occurred with
the latest tpc01 report archive, although I'm not certain it's truly specific
to this KAR.  After debugging the workflow and building the report, I found
that opening the archive and viewing the report would not trigger a message
saying the workflow needed to be run first.  Executing the workflow would then
generate a single blank page with no title or any content, but with a time and
date stamp at the bottom.  I have attached the run archive with that output in
it.

A clean-cache made the problem go away, but I can't replicate it, so I can't be
sure what went wrong or that it won't happen again.
