Migration has nothing to do with it.
https://bugs.python.org/issue29519
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=...

This seems to be fixable.
In short open /usr/lib/python3.5/weakref.py and change line 109 to:
def remove(wr, selfref=ref(self), _atomic_removal=_remove_dead_weakref):
And line 117 to:
_atomic_removal(d, wr.key)
Note you need to do this with spaces, not tabs as this will cause other errors.
