[Python-modules-team] Bug#836585: celery: FTBFS in testing (failing tests)

[Santiago Vila]

Package: src:celery
Version: 3.1.23-5
Severity: serious

Dear maintainer:

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

The failure does not seem related to using "dpkg-buildpackage -A".

Thanks.
