[Python-modules-team] Bug#850236: python-django: FTBFS (AssertionError)

[Santiago Vila]

Package: src:python-django
Version: 1:1.10.3-2
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:

--------------------------------------------------------------------------------

This is just how the build ends, not necessarily the relevant part.

I've put several build logs here:

https://people.debian.org/~sanvila/build-logs/python-django/

If this is really a bug in one of the build-depends, please use reassign and affects,
so that this is still visible in the page for this package.

The bug should be reproducible with sbuild on a single CPU virtual machine.
It always fail for me (I tried 10 times in different autobuilders), and it
also fails here:

Thanks.
