konqueror after upgrade

Hi I was using KDE 3.1.1 on my SuSE 8.1 box installed from the KDE.org and everything was OK. This morning I decided to upgrade the KDE packages to those available on SuSE's homepage. The installation (rpm -Fvh *.rpm) was OK, but now konqueror does not display anymore some web pages like www.suse.de. I remember that I had this problem also before using the packages from the KDE.org site, could somebody give me a hint to what is the problem here? Some bugs in SuSE's packages? Did someone else noticed this?
