Application: systemsettings (1.0)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-31-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
System crash dialog box appears each time the system is started.  Dolphin won't open.  Error says soprano.  Nepomuk won't start without crashing.  Can not access "desktop search" from system settings.  Trying to access this causes "system settings" to freeze.
I uncheck "Nepomuk Search Module" from kde service manager, but the problems remain.

The crash can be reproduced every time.

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