            Bug ID: 424760
           Summary: KOrganiser crash when changing calendar of an event
           Product: Akonadi
           Version: unspecified
          Platform: Ubuntu Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: ICal file resource
          Assignee: kdepim-bugs at kde.org
          Reporter: niluxv.opensource.C-h2ty6xl at yandex.com
  Target Milestone: ---

Application: akonadi_ical_resource (5.13.3 (19.12.3))

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-42-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
1. Create a new event (in some calendar `cal_a`); save (ok/apply)
2. Select this event and click edit
3. Change the calendar of the event to a different one (say `cal_b`); save
(ok/apply)
Crash reporter now reports a crash, *but KOrganiser seems to keep running
fine*; the event also did actually change its calendar

-- Backtrace:
Application: Personal Calendar (akonadi_ical_resource), signal: Segmentation
fault
