[PKG-Openstack-devel] Bug#848795: swift: FTBFS: TypeError: unsupported operand type(s) for +=: 'int' and 'str'

[Lucas Nussbaum]

Source: swift
Version: 2.10.0-3
Severity: serious
Tags: stretch sid
User: debian-qa at lists.debian.org
Usertags: qa-ftbfs-20161219 qa-ftbfs
Justification: FTBFS on amd64

Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.
