Hello,



 dl4daniel:

TypeError: ‘NoneType’ object is not callable


I think might be seeing a [bug in python 3.5 weakref]
(http://bugs.python.org/issue29519 81) that occurs during shutdown.
On my machine I was able to resolve it by applying this patch (though I seem to recall that there was some fuzz in the line numbers):
https://github.com/python/cpython/commit/9cd7e17640a49635d1c1f8c2989578a8fc2c1de6.patch 154
Best regards
Thomas
