Bug 330682

kded crashes, and it will do it again when I connect with VNC (Chicken of the VNC) to window :1 and then try to change the size of the window.

I put the backtrace in additional details because the window that offers to let me submit the backtrace requires kded to operate.

Reproducible: Always

Steps to Reproduce:
1.reboot kubuntu system configured to autologin
2.Xwindow system comes up with window offering to submit a bug report because kde deamon has crashed.
3.Try to submit bug report, cannot connect to kded (because it crashed)

KDE Platform Version: 4.11.2
