-- Information about the crash:
I have a file I edited yesterday, saved as .kra. When I open it again and try to save it, whether over the existing file, as a new version or as a .jpg, Krita crashes.

The crash can be reproduced every time.

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