python - kivy ImageRightWidget -> AttributeError: 'super' object has no attribute '__getattr__'

Question

This is a working example with image on the left.

from kivymd.app import MDApp
from kivy.lang import Builder

KV = '''
Screen:
    MDList:
        OneLineIconListItem:
            text: "yolo"
            ImageLeftWidget:
                source: "img_success.png"
        OneLineIconListItem:
            text: "yala"
            ImageLeftWidget:
                source: "img_success.png"
'''

class MyApp(MDApp):
    def build(self):
        screen = Builder.load_string(KV)
        print(screen)
        return screen

MyApp().run()

But when I want to change ImageLeftWidget to ImageRightWidget, I have this error message:

File "kivyproperties.pyx", line 863, in kivy.properties.ObservableDict.__getattr_
AttributeError: 'super' object has no attribute '__getattr__'

It looks like a fundamental bug that I can't, isn't it ?
