Bug 278160

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I have changed by command line the MAC address associated to wired network interface. After that, I selected a Wired Profile from Network Manager and suddenly Plasma crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: Shell del desktop di Plasma (plasma-desktop), signal: Segmentation fault
