In 1.10rc1 I get the following when running `./manage.py dumpdata
auth.user --traceback`::
{{{

Can you try to put together a minimal sample project to reproduce the
crash and [https://docs.djangoproject.com/en/dev//internals/contributing
/triaging-tickets/#bisecting-a-regression bisect] to determine where the
behavior changed?

Comment:
Sorry, but the project you provide is too complex and I'm spending too
much time trying to debug this. Reopen if you can put together a more
minimal project that reproduces the problem and hopefully also bisect to
find the commit where things changed. Thanks!
