Right, I just checked Policy, 5.6.12 Version:

"The package management system will break the version number apart at
the last hyphen in the string (if there is one) to determine the
upstream_version and debian_revision. The absence of a debian_revision
is equivalent to a debian_revision of 0."

When pyca_20031119-0_all.deb and pyca_20031119_all.deb are equivalent,
and pyca_20031119_all.deb is definitely a native package, we shouldn't
have accepted sth. like pyca_20031119-0.diff.gz into the archive.

Now the question is, how to handle the mess? :-)

Maybe prevent uploads of -0.diff.gz and -0.debian.tar.bz2 in the future,
and in tools like sbuild, work around the respective broken packages
with a strategy like in the patch in #687396. The case without revision
is known to be handled well. And for "-0" packages with Debian specific
diffs/tgzs, handle them as non-native package, even though this is
formally a forbidden case.

Thanks,

Roland
