With pdf.py, on each PDF I've tried so far, I get errors like below. Tips how to solve this?
For example
$ python pdf.py bezuidenhout.pdf vakantieoverzicht.pdf
error: expected 'obj' keyword (22 222 ?)
warning: trying to repair broken xref
warning: repairing PDF document
and (with the provided exampled PDF's):
sander@sammie:~/git/pocs/collisions/scripts$ python pdf.py ../examples/poeMD5_A.pdf ../examples/poeMD5_B.pdf

Installed mutool version is 1.14, so uptodate:
$ apt list --installed | grep mupdf
mupdf-tools/cosmic,now 1.14.0-0build1+ubuntu18.10 amd64 [installed]
mupdf/cosmic,now 1.14.0-0build1+ubuntu18.10 amd64 [installed]

It's normal that errors appear since the PDF was manipulated in an ugly way.
(that's why it's called hacked.pdf)
It will always say something like:
error: cannot recognize xref format
warning: trying to repair broken xref
warning: repairing PDF document
