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 Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
