Hello Guix,

When converting certain PDF files to PostScript pdf2ps (from the
Ghostscript package) will print the following error messages:

--8<---------------cut here---------------start------------->8---
   **** Error reading a content stream. The page may be incomplete.
               Output may be incorrect.
   **** Error: File did not complete the page properly and may be damaged.
               Output may be incorrect.
--8<---------------cut here---------------end--------------->8---

The resulting file will be missing some (sometimes all) of the text.

I have attached one such PDF, which I obtained from
https://www.ichkoche.at/?ctl=recipe_pdf&recipe_id=3161, alongside the
files generated by running pdf2ps on both Guix System and, for
reference, Debian 9, where the conversion succeeds (even though they
provide the same version (9.26 (2018-11-20)) of Ghostscript).

I have also attached the results of running ‘gsnd -dPDFDEBUG’ on the
offending file.

I run Guix System (commit: 0bd1498) on x86_64.

Regards,

Diego
