Paul Gevers suggested today in #debian-release: "re pyacoustid if you don't want to fix the test on s390x, please add skip the test on that arch (e.g. with an Architecture: !s390x field)"
This was after I pointed out that the autopkgtest has been failing for a long time and it was only the temporary removal of pyacoustid (because of an RC bug in a dependency) that made pyacoustid become unable to re-enter Testing. Presumably there is a real bug here, maybe endian related, but it would be nice to not hurt users on the architectures that actually use apps using this library. Thank you, Jeremy Bícha
