Both cores are on 100%

Version:           0.1
OS:                Linux

In my system the situation sometimes happens when both my processors are on 100% almost always and on the Process Table tab there are only several processes using CPU on few percents.

It looks like some hidden process (or processes) is using the CPU, but I selected All Processes.

This strange behavior appears mostly after several hours of intensive usage of my machine (CPU + memory).

Reproducible: Sometimes

Steps to Reproduce:
Use the machine intersively. After some time this behavior may appear.

Actual Results:  
Almost 100% CPU usage but no process using it can be found.

Expected Results:  
It should be visible which process uses CPU.

OS: Linux (x86_64) release 3.0.0-13-generic
Compiler: gcc

Can you still reproduce the bug?

No I cannot, but to be honest I do not use KDE very much now.
