Application: plasma-desktop (4.11.00)
KDE Platform Version: 4.11.00
Qt Version: 4.8.4
Operating System: Linux 3.11.0-3-generic x86_64
Distribution: Ubuntu Saucy Salamander (development branch)

-- Information about the crash:
- Custom settings of the application:

Possibly related to veromix plasma applet. I upgraded; noticed that veromix was missing; tried to add it to my systray, and Plasma crashed. Now it crashes on login, every time. Going to try wiping out my entire ~/.kde and ~/.config directories (sigh).

The crash can be reproduced every time.

-- Backtrace:
