When py3 applications are exiting we often see errors similar to the following: Exception ignored in: <function WeakValueDictionary.__init__.<locals>.remove at 0x7fcb56b09400> Traceback (most recent call last): File "/usr/lib64/python3.5/weakref.py", line 117, in remove TypeError: 'NoneType' object is not callable After a quick search this was found to be a well reported issue upstream and had an appropriate fix which is backported here.
