[racket] scribble secref does not render consistently between HTML and PDF

I'm writing some general documentation with scribble and have, so far,
been generating HTML output.

I'm now moving to PDF/Latex output, and the @secref calls are not being
rendered consistently between my output formats. In --html, --htmls and
--text rendering modes, secref renders the title of the section. But with
--latex and --pdf, the link destination is rendered as the section number
"section n.n" (this string is not hyperlinked, either -- something I can
half tolerate, since it's going to printed media).

Scribble's secref documentation states:

> Inserts the hyperlinked title of the section tagged tag, but elements in
             ^^^^^^^^^^^^^^^^^
> the title content with the 'aux style property are omitted in the
> hyperlink label.

My latex is:
-----------------------------------------------------------------------
$ pdflatex tim.tex
This is pdfTeX, Version 3.1415926-1.40.11 (TeX Live 2010)
restricted \write18 enabled.
entering extended mode
-----------------------------------------------------------------------

Is this a problem with scribble/latex/their interaction or my reading of
the documentation?

Help much appreciated. Thanks,

Tim
