Version:           4.6 (using KDE 4.6.1) 
OS:                Linux

Immediately after the desktop appears upon login a crash reporting window appears alerting me of kded4's crash.  This has been happening upon every login since I upgraded to 4.6.1 with the Kubuntu 10.10 PPA (x86_64).

When attempting to start from command line I get same results.  As expected, many KDE services are unavailable or complain that kded cannot be contacted.

Reproducible: Always

Steps to Reproduce:
Login
