I plan to rebase poppler in Fedora 15 and rawhide to poppler-0.16.3.
There is one API change (in PreScanOutputDev.h) and 1 soname bump
(libpoppler.so.12 to libpoppler.so.13).
You can test it against your package with this scratch-build:
I'll do chain-build of poppler and packages requiring it next Thursday
(10th of March).
