            Bug ID: 388418
           Summary: KOrganizer always crashes when one (of multiple)
                    CalDav calendars is activated
           Product: korganizer
           Version: 5.7.0
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: kde-bugs at cerritus.eu
  Target Milestone: ---

Application: korganizer (5.7.0)

Qt Version: 5.9.3
Frameworks Version: 5.41.0
Operating System: Linux 4.10.0-42-generic x86_64
Distribution: KDE neon User Edition 5.11

-- Information about the crash:
I'm having KOrganizer connected to the CalDav calendars of my OwnCloud
instance. It's six calendars in total. Five of them are working fine, but as
soon as I enable the sixth one (ticking the checkmark in KOrganizer to show the
calendar) KOrganizer crashes. It crashes again on every start as long as
showing this calendar is enabled. I assume that one of the events or tasks of
this calendar is causing the crash, but as it's the largest one, I
unfortunately don't know which event or task it is.

The crash can be reproduced every time.

-- Backtrace:
Application: KOrganizer (korganizer), signal: Segmentation fault
