The FcFontSort() routine returns fonts sorted in the wrong order. All the details are at the above URL along with a code sample which demonstrates the problem. This bug is currently causing Evince to display incorrect fonts under Ubuntu's "Hardy Heron."
I can't access launchpad. Reopen the bug if you are willing to actually report *here*.

I'm fairly sure that this bug has been fixed in poppler already.
I'm pretty sure the bug is in fontconfig and not in poppler. It looked to me like more recent versions of poppler did not exhibit the bug because they call fontconfig differently. However, the underlying bug remains in the fontconfig library and will affect other people who try to use the library. There's a fair amount of information in the Ubuntu bug report: https://bugs.launchpad.net/ubuntu/+source/evince/+bug/327757 Specifically, please see this code sample: http://launchpadlibrarian.net/22890843/fchello.c It demonstrates that FcFontSort is apparently not sorting correctly and, actually, gives a different result from what fc-match gives.
It's a bug in the fonts. See bug 17493 and discussion on https://bugzilla.redhat.com/show_bug.cgi?id=478332 *** This bug has been marked as a duplicate of bug 14883 ***
