Bug 274578

Version:           unspecified (using KDE 4.6.2) 
OS:                Linux

After resuming a session from "suspend on memory", if connected to network before the connection, kded4 consume 100% CPU (one core). I've generated a core file with gcore and the looping thread is always showing a backtrace like:

I may supply full cores if needed.

Reproducible: Always

Steps to Reproduce:
Connect on network, both wired and wireless. Suspend on ram. Resume the PC.

Actual Results:  
most kde functionalities not working. kded4 uses 100% CPU

Expected Results:  
Works like a charm :-)
