Description of problem: poppler is available at 0.20.0 but Fedora's languishes behind at 0.18.4. updated poppler available from http://poppler.freedesktop.org/poppler-0.20.0.tar.gz
Fedora's builds have backported fixes (fyi), and I believe the decision was made not to rebase f17 to 0.20 because it introduced ABI changes too late in the fedora development cycle.
and as a testment to that, we've already introduced poppler-0.20 into rawhide (to be come f18), and the build breakages have yet to still be fully resolved.
