"i remember seening a forum post somwhere saying that you had to recompile some part of kde,"
Kde and Qt are very version dependent. You have to upgrade the entire KDE and the entire Qt at the same time. So you need to upgrade your entire KDE to the vesion level that corresponds with QT 3.2.3.
When you have a mixture of KDE and/or Qt versions then you get weird errors in the appearance of your desktop and your application windows.
Be prepared. Create a LifeBoat CD.
