Upgrade to KDE3.1.4 messed up some fonts

After the upgrade to KDE 3.1.4 on my SuSE 8.2 box some fonts seem to have disappeared. KNode and some text parts on web pages in Konqueror now look jagged and ugly again, just like a typical Linux system 2 years ago. In KWord the list of fonts is still there but some are dead, i.e. if you change a font in a text then nothing happens. Helvetica is gone, Verdana is still there. Does anyone have any clue which config file or setting could be responsible for this? (I really hate this aspect of Linux, with each upgrade entire config files are thrown out and replaced, ugh).
