Bug 414596

Application: kolourpaint (19.04.3)

Qt Version: 5.12.5
Frameworks Version: 5.61.0
Operating System: Linux 5.3.12-300.fc31.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
I have created a new image, but through the file manager I've deleted the image on disk and it crashed.
This is not normal, but at least a safeguard to not let this happen would be nice.

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