Evince in Raring Ringtail (upcoming Ubuntu) is
GNOME Document Viewer 3.6.1
and definitely shows the problem.  Libraries are
ii  libcairo2:i386 1.12.14-0ubu i386         The Cairo 2D vector
graphics libr
ri  libpoppler28:i 0.20.5-1ubun i386         PDF rendering library

xpdf (from several versions back, the last one that does not just
segfault) too.
