Frameworks Version: 5.41.0
Operating System: Linux 4.10.0-42-generic x86_64

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

1. Have a unsaved, modified document.
2. Close krita.
3. Click 'yes' when Krita asks whether you wanna save the document.
4. Krita crashes in the end.

The crash can be reproduced sometimes.

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