I plan to rebase poppler in rawhide to poppler-0.24.0 at 19th of August.
There are several changes and 1 soname bump (libpoppler.so.37 to
libpoppler.so.43). It also adds support for Qt5.
I've prepared a scratch build of poppler-0.24.0 against which you can
test your packages. You can find the build here:
