Description Thiago Sueto 2020-10-12 00:33:49 UTC 
Application: kontact (5.15.40 (20.11.80))

Qt Version: 5.15.1
Frameworks Version: 5.76.0
Operating System: Linux 5.8.14-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Attempted to add a new task to KOrganizer in the "Enter a summary to create a new to-do" field.
Kontact/KOrganizer crashes from this. Zanshin doesn't, but it fails to add tasks.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault

I can't reproduce this with 5.15.2 on KDE Neon.

I created my task in a local ICS file.  What type of calendar did you use?

Terminal log

Hello, I used the standard iCal calendar that KOrganizer creates after clicking Add Calendar...
It also happens when I attempt to add a to-do task to my google My Tasks.

Here are my terminal logs for it (fetched using the command korganizer 2> korganizertodocrash.txt)
Comment 3 Thiago Sueto 2020-11-02 16:07:52 UTC 
No longer reproducible on master for both openSUSE Krypton and KDE neon.
Comment 4 gjditchfield 2020-11-02 19:34:35 UTC 
Maybe Daniel Vrátil fixed it:
