TypeError: Error when calling the metaclass bases multiple bases have instance lay-out conflict

in my conda env: python -c "import gnuradio.wxgui.forms" results in:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "forms.py", line 64, in <module>
    class _form_base(pubsub, wx.BoxSizer):
TypeError: Error when calling the metaclass bases
    multiple bases have instance lay-out conflict

no conda env: python2 -c "import gnuradio.wxgui.forms" works correctly

Any ideas how I can solve this?

Same issue, no idea why.
