Minimize / Restore / Quit - Buttons after Update not available

Hello,

on my Desktop I've installed Suse Linux Professional 10.0 and today I updated KDE to the version 3.5.3.

Since the update via mirror-server/pub/linux/suse/ftp.suse.com/suse/i386/supplementary/KDE/ update_for_10.0/yast-source/ doesn't work I tried to update as described in http://en.opensuse.org/Build_Service/User (YaST2)

After the update I have the "problem", that the "icons" for minimize, restore, quit are "empty / plain" (see attachment).

Can somebody tell me, how I can solve this?

Thanks, Bernhard
