[Python-modules-team] Bug#916873: python-twisted-core: Incorrect versioned dependency on python-attr

[Kurt Roeckx]

Package: python-twisted-core
Version: 18.7.0-2~bpo9+1
Severity: serious

Hi,

With python-twisted-core and python-attr 16.3.0-1, I get the
following error:
[...]
  File "/usr/lib/python2.7/dist-packages/twisted/web/http.py", line 100, in <module>
    from twisted.internet import interfaces, protocol, address
  File "/usr/lib/python2.7/dist-packages/twisted/internet/address.py", line 23, in <module>
    class IPv4Address(object):
  File "/usr/lib/python2.7/dist-packages/twisted/internet/address.py", line 37, in IPv4Address
    type = attr.ib(validator=attr.validators.in_(["TCP", "UDP"]))
AttributeError: 'module' object has no attribute 'in_'

Upgrading python-attr to the version from backports (17.4.0-2~bpo9+1) works.
