KDE 3.3 Eats all CPU

Hi, since upgrading to the new KDE 3.3 I've found that kdeinit is using 100% of the CPU. I'm running a dual PIII 500 machine with 256MB RAM. I would have thought that this was sufficiently powerful enough to run Suse 9.1/KDE. It didn't use as much CPU before the upgrade. Any ideas? Matthew
