Bug forwarded from Evince: http://bugzilla.gnome.org/show_bug.cgi?id=510504
"Please describe the problem:
In the following document:
you should see a red curve, a green curve and some vertical blue bars (they all
display fine with xpdf). However, evince doesn't display the blue bars.
(evince 2.20.2 with poppler 0.6.3 (cairo))"
I can confirm it's only reproducible with cairo backend, it works with splash.
I think this is a similar problem than line width < 1.0 (see bug #4536). Those vertical blue bars are rectangles with width < 1.0.
