Kontact refuses to re-start

Hello. 

I'm running OpenSuse 11.2 64 bit on a Lenovo T61 and using the KDE4 desktop.

For the most part, it's working fine. Sound, connecting, even DVDs all work 
OK.

What doesn't work OK is Kontact KDE-PIM. It starts up OK and behaves normally 
until I shut it down. Then it refuses to re-start - the icon bounces for a 
while, then goes away, and nothing happens. The only way I can get it to start 
again is to log off my session and restart it.

I looked for problems reported and note some of it appeared to relate to 
having the kontact item in the tool bar so I removed it from there but left it 
in it's normal menu position. That doesn't appear to make any difference.  

Anyone else have this problem?
