Application that crashed: krdc
Version of the application: 4.3.00 (KDE 4.3.0) "release 158"
KDE Version: 4.3.00 (KDE 4.3.0) "release 152"
Qt Version: 4.5.2
Operating System: Linux 2.6.27.23-0.1-default x86_64

What I was doing when the application crashed:
Happens every time I log off and then press the disconnect button in fullscreen mode of a RDC session. I don't have any VNC server to try this with so I can't say if it is also happening with that protocol.
