Have the same issue, anyone have an idea of a workaround on Arch Linux?

[bquast]

I uninstalled pypdf2 v. 3.0.1 and installed pypdf (all smalls) 2.12.1, then it works

I suppose this is already fixed in krop but they just haven't made a release with the fix yet. See: arminstraub/krop#39

@leenaars, since upstream hasn't released an update with the commit which fixes this issue, would you consider updating the Nix package to use a commit as the version, rather than using the "0.6.0" tag?

You can probably use the current master as the commit.
