More precisely, zigos-package *Build-Depends* on python-openssl, so a
more appropriate subject for this would have been "Making build-depends
versioned to avoid *FTBFS* bugs".

I consider this distinction important, as this is not just an "ordinary bug",
it's a bug which breaks our promise that a source package will build
from source provided its build-dependencies are fulfilled.

Thanks.
