I have had the same problem under Gnome on Ubuntu.
I discovered via the KDE list that Fedora users were short of the Oxygen font library so I added oxygen-icon-theme. I now have fonts.
My first try was to add the optional/recommended KDE-Help system. That didn't help and help didn't work, so I removed it again.
