Everytime you mess with /etc/network/interfaces you have to restart NetworkManager and I mean the NetworkManager daemon, not Plasma NM.

The crash happened even after rebooting.

Comment 3 Lamarque V. Souza 2013-07-09 16:35:43 UTC

This crashlog is typical of NetworkManager crashing or in "starting" state when Plasma NM is starting. You could workaround it if you make sure NetworkManager is already started before logging in your KDE session.
