Noticed it yesterday during the changes to poppler and xpdf when I was seeing what package needed xpdf still. System is working fine with the pdfinfo from poppler-0.4.3-r1, just wants to pull xpdf back in still which only installs /usr/bin/pdftoppm now if you have -X set for it. This would be for the kdegraphics-kfile-plugins-3.5 (~arch) ebuild right now but would affect the 3.4 versions too if this version of poppler and xpdf went stable.
The dependency on xpdf in kdegraphics-kfile-plugins is wrong, it should be in kpdf-3.4.3. Should be fixed now.
