Django-hotsauce/ZODB 5.4.0/PyPy nightly sprint!!

[Etienne Robillard]

Yo people I'm doing a nightly hacking sprint for django-hotsauce on pypy 
and got some cool bugs I would like to share:

Traceback (most recent call last):

Not sure about this first one! :)

The command I'm trying to run is:

% schevo db evolve --app blogengine2 zodb://127.0.0.1:4545 31

The ZODB 5.4.0 server then produce the following traceback:

Please hit me up if you know how to fix theses errors! :)

I'm using PyPy 5.9 and 5.10 for dev and Python 2.7.13 for production 
with Cython bindings!
