Likely this is due to Python 3.7 having become a supported Python
version and Python 3.7 having changed behaviour wrt. generators.

Control: fixed 911873 python-pygraphviz/1.5-1
Hi,
I cannot reproduce this bug by building python-transitions in a fresh
buster pbuilder environment. I've updated upstream's CI setup to run on
Python 3.7, and all tests pass there as well.
Looking closer at the stack trace and the source code, it becomes clear
that `container` is a pygraphviz object, and this bug really is a
duplicate of #914378, which was fixed by python-pygraphviz 1.5-1 back in
November.
Sorry for not looking into this bug before the soft freeze.
