Created attachment 59601 [details] syslog info related to the problem Version: 4.6 (using KDE 4.6.2) OS: Linux Kded4 hanged when I plugged out my USB network adapter. Reproducible: Didn't try Further descripion available here: https://bugs.launchpad.net/ubuntu/+source/plasma-widget-networkmanagement/+bug/741200 Had to kill kded4 manually, but was not prompted to send a bug report. Could not access network afterwards (network manager widget did not show any networks available, even though my internal notebook Wi-Fi adapter did not stop working) and had to relogin. syslog.txt is attached. Tried to plug the adapter in and out.
Probably there is bug in ntrack: https://bugs.launchpad.net/ntrack/+bug/755608
