Application: kcmshell4 (4.13.0)
KDE Platform Version: 4.13.0
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic i686
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
- What I was doing when the application crashed: After clicking OK and Apply to have the Date and Time Control Module use the North American NTP server, I see a dialogue screen notifying me that the module has crashed and prompting me to report the crash to KDE developers. I've seen crashes like this before; there seems to be an unaddressed bug somewhere that has persisted through many versions of the KDE SC.

-- Backtrace:
Application: KDE Control Module (kcmshell4), signal: Segmentation fault
