[PKG-Openstack-devel] Bug#834676: python-oauth2client: FTBFS in testing ('module' object has no attribute 'SubfieldBase')

[Santiago Vila]

Package: src:python-oauth2client
Version: 2.0.1-3
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.
