[PKG-Openstack-devel] Bug#834685: python-reno: FTBFS too much often (failing tests)

[Santiago Vila]

Package: src:python-reno
Version: 1.3.0-3
Severity: serious

Dear maintainer:

I tried to build this package with "dpkg-buildpackage -A"
(which is what the "Arch: all" autobuilder would do to build it)
but it failed:

Because this source package only generates "Arch: all" packages, this
is the same as a FTBFS bug in the usual sense and the fact that I was
using "dpkg-buildpackage -A" is quite irrelevant.

For this particular package, I've also checked that it fails to build
from source in the reproducible builds site:

Thanks.
