If the invalid contents of this object is the problem,
then it raises the questions:
* What is the relation to class beamer?
  The same problem should be caused by

% "pdftex --ini" or "pdftex" or "pdflatex"
\catcode`\{=1
\catcode`\}=2
\pdfoutput=1
\immediate\pdfobj{concordance}
\shipout\hbox{}
\csname @@end\endcsname\end

* Why is the PDF reader complaining in the first place,
  the object is not referenced?

Yours sincerely
