Application: korganizer (5.9.0)

Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.17.15-gentoo-r1 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:

In KOrganizer (standalone), I changed the color of TODO incidents that are due today, via [translated from German:] Settings -> Configure Korganizer -> Colors and Fonts. A click on Apply crashed the application. I reproduced it like this two more times, without doing anything else between starting KOrganizer and setting the color.

After each crash, the color that I last chose before the crash for due TODOs, so at least the new setting was saved.

The crash can be reproduced every time.

-- Backtrace:
Application: KOrganizer (korganizer), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
