cairo: invalid matrix for PDFs with UU CS LaTeX beamer theme
Submitted by ray..@..il.com

Description
Slides created with a LaTeX beamer theme used by (part of) the CS department of Utrecht University fail to render correctly with poppler-0.20.x. The first page shows the background colors, subsequent pages are just gray. Text is invisible unless selected. I can neither see nor click the beamer navigation elements (or other images).
Example pdfs: all slides (except the last, since it's .ppt) available on http://www.cs.uu.nl/wiki/bin/view/Apa/CourseSchedule
Tested using evince/zathura. When run from a terminal, the error "Internal Error: cairo context error: invalid matrix (not invertible)" shows up repeatedly. Downgrading poppler and poppler-glib to 0.18.4 (all with Arch Linux packages) 'fixes' it. As far as I can tell, I have had cairo-1.12.2 since I first noticed this issue (but also with the working poppler-0.18.x).
(same problem with daily image of Ubuntu 12.10 amd64, which should also be 0.20.x)
