Application: systemsettings (4.11.8)
KDE Platform Version: 4.13.0
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
- What I was doing when the application crashed: Update automatic time server information to time-c.timefreq.bldrdoc.gov, selected 'Apply' and tried to close 'System Settings'.  System setting then notified me that I changed 'Time' and would I like to 'Apply' or 'Discard'. I then hit apply again to the query window; did nothing but go away.  I then hit 'Apply' again in the Time window and experienced the crash.  This can be duplicated on demand.

- Custom settings of the application: just removing pool.ntp.org and adding time-c.timefreq.bldrdoc.gov

The crash can be reproduced every time.

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