KDE 4.9 listens on external ports



Hello,

I'm currently using KDE 4.9 from qt-kde.debian.net and so far the packages all 
seem to work well, so thanks for them!

However I noticed that some KDE processes started to listen on external Ports. 
Here is my output from "lsof -n -i -P":

This seems to be some kind of UPnP or something similar. I tried to disable it 
somehow, but couldn't find a configuration switch anywhere.

In my network I don't want to use UPnP and it doesn't make sense for me to use 
it, so I just want to disable it.

So I'm asking if anybody has experienced similar behavior or knows how I can 
disable it. I did search on the internet but couldn't find anything useful 
about this. I think this started with the upgrade to KDE 4.9, through I'm not 
100% sure.

Greetings and thanks for your work,
Maxi
