Just as v. quick experiment, I extracted images_helpimg.zip from the
libreoffice-help-common package and my local strip-nondeterminism
checkout from Git was able to normalise it:

  $ cp images_helpimg.zip  images_helpimg.orig.zip 
  $ PERL5LIB=lib/ bin/strip-nondeterminism --verbose -T 503575200 images_helpimg.zip 
  $ diffoscope images_helpimg.orig.zip images_helpimg.zip | grep 85-Dec | head

Can you confirm that? From an admittedly *very* quick glance at the packaging, I
don't actually see a call to strip-nondetermism, and none seems to be implied
via dh(1). I could very easily be missing something.


Best wishes,
