PDF test case

This was reported in GNOME Bugzilla (evince), however, this bug belong to
poppler.
I can reproduce it with poppler-glib-demo, when it renders the pdf.

I tried with master (b72c02d1a2e), from Sep 13, 2012.  Here is the origina
report:


This file was generated by mathematica 8.0.4, and when I view it directly with
evince or embed it in a LaTeX PDF and view that, I get error messages on the
console

Error (220): Arg #0 to 'm' operator is wrong type ((null))
Error (223): Arg #0 to 'l' operator is wrong type ((null))
Error (225): No current point in lineto
Error (227): Arg #1 to 'l' operator is wrong type ((null))
Error (252): Arg #0 to 'm' operator is wrong type ((null))
Error (252): Arg #0 to 'l' operator is wrong type ((null))
Error (252): No current point in lineto

etc.  I don't know whether the PDF is malformed or if there's some corner case
that evince doesn't cover or what.  Mathematica does sometimes create strange
files with things like infinite rectangles for the background.  The problem
seems to be mostly harmless-- the picture looks okay on the screen and in
print.  But I thought I should report it.
