Bug 319992

Application: systemsettings (1.0)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-21-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
I called: sudo /etc/init.d/networking restart
After this call it is not possible to open kde network settings.
- Unusual behavior I noticed:
After this call some icons (kde menu) at the shutdown menu are missing:
The only visible icons are "logout" and "lock" or in German "Abmelden" and "Sperren"
After this call the icons of "Nepomuk" and "Akonadi" at the right side inside the "control-bar" are visible instead of inside the hidden icons.
Some minutes later the icons of "Nepomuk" and "Akonadi" are hidden again.

The crash can be reproduced every time.

-- Backtrace:
Application: Systemeinstellungen (systemsettings), signal: Segmentation fault
