I get this error when installing any plugin or update:
Code
Exception ignored in: <function WeakValueDictionary.__init__.<locals>.remove at 0xb6e96dac>
Traceback (most recent call last):
File "/usr/lib/python3.5/weakref.py", line 117, in remove
TypeError: 'NoneType' object is not callable

Done ...
I'm pretty lost with this problem
