Application: krita (3.1.3)

Qt Version: 5.7.1
Frameworks Version: 5.34.0
Operating System: Linux 4.8.0-53-generic x86_64
Distribution: KDE neon User Edition 5.10

-- Information about the crash:
- What I was doing when the application crashed: Typed some text, highlighted it, then went to the Tool Options docker panel. Clicked on the list of fonts and used the mouse scroll wheel to scroll down the list. Krita shuts down.

The crash can be reproduced every time.

-- Backtrace:
Application: Krita (krita), signal: Segmentation fault
