            Bug ID: 443214
           Summary: KOrganizer segmentation fault when creating new
                    caldendar event with multiple reminders
           Product: korganizer
           Version: unspecified
          Platform: Compiled Sources
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: telans at posteo.de
  Target Milestone: ---

Application: korganizer (5.18.1 (21.08.1))
 (Compiled from sources)
Qt Version: 5.15.2
Frameworks Version: 5.86.0
Operating System: Linux 5.14.6-tkg-cfs-llvm x86_64
Windowing System: X11
Distribution: Gentoo/Linux
DrKonqi: 5.22.90 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
1. Double-clicked an empty timeslot to create a new event.
2. Add multiple meeting reminders (5, 2, 1 days before start) etc.
3. Click to modify the reminder, close without changing anything.
4. Click "Apply". Notice the "Okay" button goes dull and application crashes.

I cannot reproduce this every single time, it seems to be a 10% chance at
hitting this for me.
I believe I've generated a semi-useful trace report but I still see a few
unknown symbols in there so I'll try get that updated.

The crash can be reproduced sometimes.

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