Kontact/kde-pim new problem

[Anne Wilson]

Today kontact will not launch, although kmail and korganizer launch perfectly 
well stand-alone.  I'm assuming that yesterdays updates have upset 
something - possibly the selinux-policy changes?  audit.log is showing a lot 
of denials and failures.  Attempting to launch kontact from a terminal gives

WeaverThreadLogger: thread (ID: 2) suspended.
WeaverThreadLogger: thread (ID: 3) suspended.
WeaverThreadLogger: thread (ID: 4) suspended.

*** KMail got signal 11 (Crashing)
[anne@david ~]$ KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = kontact path = <unknown> pid = 19533

'locate QDir' merely returns to the prompt.

Anyone else seeing this?
