okular for kde 4.4.0-win libpoppler has dependency on libopenjpeg, but it wasn't installed by installer, I manually unpacked tarball from 4.3.0 (openjpeg-1.3-1-bin.tar.bz2) and Okular has successfully opened PDF file.
Patrick?
sorry, yes, this is fixed now. Thanks for the bug report.
This still persists in nightly builds too. Please fix it there too, thanks.
