New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.8.3 (4.8.3) using Qt 4.8.2

- What I was doing when the application crashed:
playing around with veromix settings, after unlocking widgets.

Please all, the Veromix widget is a 3rd- party widget written in python, please report this to it's author.
