Dear Maintainer,

See this salsa build job comparing the "allabout.pdf" file:
https://nikolas.pages.debian.net/-/gnubg/-/jobs/9808951/artifacts/debian/output/diffoscope.html

diffoscope emits this message:

./usr/share/doc/gnubg/allabout.pdf
Command `'dumppdf -at {}'` failed with exit code 1. Standard output:
    Traceback (most recent call last):
      File "/usr/bin/dumppdf", line 468, in <module>

      File "/usr/bin/dumppdf", line 454, in main

after installing the following packages in the debrebuild job on salsa:
  poppler-utils python3-pdfminer xxd

This appears to be a pdfminer bug. The fix is here:
https://github.com/pdfminer/pdfminer.six/pull/1270

Hey Nikolas,

Thanks for tracking this down and submitting a fix. :)  I'll let the
pdfminer folks fix this in "their" package rather than applying any
kind of workaround to diffoscope. 👍


Best wishes,

We can consider making a debian patch for pdfminer for now - upstream
has not moved yet, but the fix is quite straightforward:

https://github.com/pdfminer/pdfminer.six/pull/1271/changes

I will maybe come up with the merge request in salsa with these changes
if that's helpful.

Hello Nikolas,
Thanks for your report and sorry for my late reply. I hope to be able to
work on this on Sunday.
No need to come up with a merge request if you don't have time right
now. I hope to upload it on Sunday.

Cheers,
Daniele

Hello,
