Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-20-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Widget would not respond to pressing the "Configure" button located in the middle of the Personal screen.  Looked like plasma crashed. Screen went dark and then came back with the crash handler appelate.

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
