Bug 279628

Version:           4.6 (using KDE 4.6.5) 
OS:                Linux

Ever since the last update from 4.6.4 to 4.6.5 (with yum update from FC15 repository) I started to get kde daemon crash every time I login.

Reproducible: Always

Steps to Reproduce:
Logout of reboot, then login to KDE. Also happens if I try to start kded4 manually.

Actual Results:  
Receive a window with the warning information on crash. Here's the message in the terminal when I try to start it manually:
