Bug 267426

Application: systemsettings (1.0)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-27-generic x86_64
Distribution: Ubuntu 10.10

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

Clicked on User Management from inside System Settings, churned the CPU for about ten seconds then crashed, but User Management still loaded in a separate window.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
