I don't have KDE so I can't test. But I did find this link: http://forum.kde.org/viewtopic.php?f=20&t=91242It looks like portfolio PDFs are not supported, although someone there mentions a possible hack. okular apparently uses poppler as the backend. Poppler is a fork of xpdf-3.0, so we're back to square one.
