Hi,

This package fails to build a source package after a successful build
(dpkg-buildpackage ; dpkg-buildpackage -S).

This is probably a clear violation of Debian Policy section 4.9 (clean target),
but this is filed as severity:minor for now, because a discussion on
debian-devel showed that we might want to revisit the requirement of a working
'clean' target.

More information about this class of issues, included common problems and
solutions, is available at
https://wiki.debian.org/qa.debian.org/FTBFS/SourceAfterBuild

For some reason I thought that the whole "python binary cache" thing was sorted automatically by dh. But it turns out I was able to fix this by just adding that directory to debian/clean, which seems simple enough. It is in git on salsa and will be in the next upload of the package: this did not seem substantial enough to merit a release.
