No screensavers anymore after update to KDE 3.4.2

HI! After updating my Suse 9.2 from KDE 3.4.1 to 3.4.2, one of the users (only this one) has an empty list of screensavers. It still works OK for other users! I tried to rename .kde with no positive effect. Out of the blue, I restored a Suse 9.0 user directory from that user and started with that and the screensavers where there again! Then, with the 9.2 user directory, they were there, too. After working for a few days, the list of screensavers is empty again for that user. What can that be? Thanks! Thomas
