Sentry Crash Report:

Description mmesic.ing 2020-03-13 08:36:17 UTC 
Application: kontact (5.13.3 (19.12.3))

Qt Version: 5.14.1
Frameworks Version: 5.67.0
Operating System: Linux 5.0.0-37-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.18

-- Information about the crash:
- What I was doing when the application crashed:
Opening Settings -> Configure Kontact


- Custom settings of the application:
This may be related to changing calendar event colours through the settings menu. Since the Birthdays & Anniversaries calendar colour can't be changed directly in KOrganizer, I changed it through the settings menu. Crashes appeared after that on two separate installs.

The crash can be reproduced every time.

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