Bug 286857

Version:           unspecified (using KDE 4.7.3) 
OS:                Linux

I use KDE SC 4.7.3, kdelibs are compiled with UPNP support through Herqq. FWIW, I have also kio-upnp-ms and Cagibi installed. My laptop is in a network with several dozen UPnP servers (most are Windows Media Player, some are foobar2000) and a couple of foobar2000 UPnP renderers. Sometimes, usually once in a couple hours, multiple KDE-related applications, for example knotify and krunner, crash at the same moment. I don't need to do anything to achieve that - it's probably caused by network traffic.

Example backtrace:

Application: Interfejs do uruchamiania poleceń (kdeinit4), signal: Segmentation fault
