Application: systemsettings (1.0)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.5.0-18-generic i686
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
 Configuring a new time server (pool.ntp.org). This crash was repeated 2 times. 

And even without crash, the time server is not saved. If I enter “pool.ntp.org” as a time server, the app say (in French, sorry): “Impossible d'authentifier / d'exécuter l'action : 6, ” (Translation: “Unable to authenticate / execute the action : 6, ”). And I receive the same message for “europe.pool.ntp.org”.

The crash can be reproduced some of the time.

-- Backtrace:
