            Bug ID: 304034
          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: unassigned-bugs at kde.org
           Summary: setting update time automatically and then hitting
                    okay twice causes crash
    Classification: Unclassified
                OS: Linux
          Reporter: illumilore at gmail.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: systemsettings

Application: kcmshell4 ()
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.5.0-030500rc6-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed: when setting the update time
to automatic in adjust date and time window, and then hitting okay twice right
after that, a crash occurs.

The crash can be reproduced every time.

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