KDE 3.0.3 upgrade problems

After installing the KDE upgrade as per 
http://www.suse.com/us/private/download/linuks/i386/update_for_8_0/index.html
certain apps crash.

For example find files

the Crash Handler dump says:

Similar output is given when some apps like package manager encounter a 
problem such as a zero result for a search.

But the worst of the problem is that Yast2 will not start.  The sand 
clock revolves for a while .......then nothing.

I first noticed that Yast2 was sick when I was going to reinstall webcam 
apps which would not load.  i.e. the KDE 303 upgrade did something to 
the webcam (video) apps.

Since Qt3 looks to be involved I installed it again and the option Qt3 
stuff , to be sure.  But it has not helped.

Main apps such as StarOffice, QCad, Mozilla, Digikam are OK

I will post this Suse-kde list.  ....... After a quick look ....it seems 
that KDE 3.0.3 is now old.

Any suggestions

1) to stop the crashes

2) regain "lost" apps like Yast2
