Test file, the last page should show "OK" in all nameref links:

The following code from memhfixc explains Victor's remark,
that adding \usepackage{nameref} works:

|  \AtBeginDocument{%
|    \@ifpackageloaded{nameref}{\let\nameref\titleref}{}%
|  }

With \usepackage{nameref} this code redefines \nameref.
Otherwise, hyperref loads nameref later using \AtBeginDocument.

In any case, this code is unhappy, because hyperref has
to define a star variant of \nameref, see Victor's other problem.
