Application: systemsettings (1.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-25-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
Fresh Kubuntu 10.04 install on an old Compaq nc4010. Just trying to get to System Settings from the Kickoff app launcher to add a new user. It worked once before, PRIOR to adding the 100+ bug fix and security updates right after the install when I went there to switch from"Air" to "Oxygen" in workspace settings. Can't think of anything else that may have changed other than the rather large set of updates after the initial install.

The crash can be reproduced every time.

 -- Backtrace:
Application: System Settings (systemsettings), signal: Illegal instruction
