            Bug ID: 321215
           Summary: Clock crashing when setting to get time from time
                    server
    Classification: Unclassified
           Product: systemsettings
           Version: 4.10.3
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: bot1968 at msn.com

Application: kcmshell4 (4.10.3)
KDE Platform Version: 4.10.3
Qt Version: 4.8.4
Operating System: Linux 3.8.0-25-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
This happens when I try to set the clock to get the time automatically from any
time server. I guess it is related to the iMac where Kubuntu is installed on,
since it did not happen in the years before, when I used an Intel laptop for
Kubuntu. Also setting the timezone does not get any desired result (display the
right time it does not). When I set the time manually, it is wrong again after
reboot.

The crash can be reproduced every time.

-- Backtrace:
