            Bug ID: 352899
           Summary: Clock crashed after switching date format and resizing
                    the bar
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: FabianRoth64 at googlemail.com

Application: plasma-desktop (4.11.11)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.19.0-28-generic x86_64
Distribution: Ubuntu 14.04.3 LTS

-- Information about the crash:
During customizing the bar only parts of the clock became visible.
I changed the hight of the bar so check if that would fix it, then it crashed.

-- Backtrace:
Application: Plasma-Desktop-Umgebung (plasma-desktop), signal: Segmentation
