Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 3.1.1 x86_64
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
- What I was doing when the application crashed:

I have connected the Ethernet cable, when KDE session was already opened, and another network connection (via WiFi already existed).
This was the first time, when such situation occured (even though I often connected/disconnected Ethernet cable while using WiFi).

-- Backtrace:
Application: Powłoka pulpitu Plazmy (plasma-desktop), signal: Segmentation fault
