This is a bug. You can report it at Issues · GNOME / Document Scanner · GitLab


Got to MenuPreferences, and disable Enable Postprocessing.

I think you’ve enabled the option without providing any post-processing script.

That’s right, I enabled it thinking that it might enable editing the image. Switching it off will fix it for me.
I tried reporting it as a bug, but it wouldn’t accept my GitHub account. I’ll leave it to someone who has the sort of account they want.
