I'm using KBibTex (the KDE4 version) to manage my references for some thesis work. It is not in the repos for Ubuntu 11.10, but I installed it without problems using the v. 0.4-beta1 deb from Debian's repos here: http://packages.debian.org/sid/kbibtex.
The only thing that seems not to work is the PDF-preview, which states "Cannot create preview for [file]. No part available."
I suppose it relies on some KDE PDF-viewer, but what do I install to make it work?
I should mention that I'm running the regular Ubuntu 11.10 with Gnome and Unity, not KDE.
