Exception ignored when installing any plugin

I am running OMV 4.0.16-1 and whenever I install a new plugin I got the following error in the dialog window:

Exception ignored in: <function WeakValueDictionary.__init__.<locals>.remove at 0x7f26a447c8c8>


Traceback (most recent call last):


  File "/usr/lib/python3.5/weakref.py", line 117, in remove


TypeError: 'NoneType' object is not callable


Done ...

Content of line 117 in weakref.py:

def remove(wr, selfref=ref(self)):
            self = selfref()
            if self is not None:
                if self._iterating:
                    self._pending_removals.append(wr.key)
                else:
                    # Atomic removal is necessary since this function
                    # can be called asynchronously by the GC
                    _remove_dead_weakref(d, wr.key)

Everything works as expected after it.

Is it a common behaviour? Does it imply anything wrong?

Thanks in advance.

This is a bug in the Debian Python package. If you like, then report is to the Debian project, otherwise it will not be fixed by them.

Thank you.

I will read how to report it as I had never done it before
