Hi Sebastian,

Thank you for reporting this!  I have tracked the problem down to an
upstream bug in Archive::Zip which affects Zip files containing bzipped
members:

https://github.com/redhotpenguin/perl-Archive-Zip/issues/26

Until this is fixed, the -X option is a good workaround.  Since this
file presumably comes from the source and is not a build product,
there's not any non-determinism that needs to stripped from it anyways.

Cheers,
Andrew
