PDF test case

This bug was reported in https://bugzilla.gnome.org/show_bug.cgi?id=680766

"Evince doesn't show page labels correctly.  The attached PDF contains the statement

/PageLabels<</Nums[0<</S/a>>1<</S/r>>]>>

which indicates that the first page's label is "a", and the second page's label
is "i". However, for the first page, evince shows an empty label, for the
second page it correctly shows "i". It might be a bug in poppler and not
evince. Not sure about that.

The latex code to create the attached PDF file:

\pdfcompresslevel 0
\pdfobjcompresslevel 0
%\listfiles
\documentclass{article}
\usepackage{hyperref}
\begin{document}
\pagenumbering{alph}
Test
\newpage
\pagenumbering{roman}
Test
\end{document}
"

When I open the PDF file with poppler-glib-demo and I try to get the information for each page, I only get the Page Label for the second page ('i'), but the first one is empty.

I do not know whether this problem is specific to the glib fronted or is general.

FWIW, I tested it with poppler master (df35562)
