Description James Beddek 2021-10-02 02:28:56 UTC
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

This is hard to reproduce, of course.  I have a few questions.

- Step 3:  do you close by clicking OK, or Cancel, or ... ?
- "10% chance":  is that 10% of event creations, or of reminder modifications?
- The crash seems to start with a call to IncidenceEditorNG::AttendeeTableModel::setAttendees.  Did your events have any attendees?

(Note: bug 428888 and bug 413978 also have setAttendees in their stack traces.)

I thought it was through OK, but I just replicated it with "Cancel" so I assume it's that

I should have clarified, a 10% chance of the application crashing, although the event is still created with all reminders in place.

I haven't added any attendees, however this crash seems very reproducible just by clicking on the "Status" and "Response" selections for a blank attendee without changing anything. Perhaps try this before adding the reminders?

Cheers

Crash on my first try.  Progress, of a sort!

Bug 446378 is another setAttendees() crash.

New crash information added by DrKonqi

kontact (5.19.3 (21.12.3)) using Qt 5.15.2

- What I was doing when the application crashed:

Adding a meeting member as Leader of the meeting.
 * Possibly the instability is affected by IncidenceEditorNG::AttendeeTableModel::setAttendees
