Error using MDRecycleGridLayout and MDFabButton

[Fector101]

Description of the Bug

Anytime i try add Widget to the MDRecycleGridLayout i get an error, I tried using a plain kivy Button and it works each time but when i use MDFabButton it works 1 of 10 times or consistently dosen't work.

I tested on linux and compiled for android same result.

Code

from kivy.uix.behaviors import ButtonBehavior
from kivy.uix.image import AsyncImage
from kivymd.uix.recyclegridlayout import MDRecycleGridLayout
from kivymd.uix.recycleview import MDRecycleView
from kivy.uix.screenmanager import Screen
from kivymd.uix.button import MDFabButton
from kivymd.app import MDApp


class Thumb(ButtonBehavior, AsyncImage):
    pass


class TestApp(MDApp):

    def __init__(self, **kwargs):
        super().__init__(**kwargs)
        self.rv = None
        self.view_data = [{'source': 'img1.jpg'}]

    def build(self):
        screen = Screen()
        self.rv = MDRecycleView()
        grid = MDRecycleGridLayout(
            cols=3,
            default_size=(None, 120),
            default_size_hint=(1, None),
            size_hint_y=None)
        grid.bind(minimum_height=grid.setter("height"))
        self.rv.layout_manager = grid
        self.rv.viewclass = "Thumb"
        self.rv.data = self.view_data

        self.rv.add_widget(grid)
        screen.add_widget(self.rv)

        btn = MDFabButton(icon="plus", on_release=self.copy_add)
        screen.add_widget(btn)
        return screen

    def copy_add(self, instance):
        for each in ['img.jpg']:
            self.view_data.append({"source": each})
        self.rv.data = self.view_data


if __name__ == '__main__':
    TestApp().run()

Edit

I create, inherited and added the property's to Stop the Bug

class MyMDRecycleGridLayout(MDRecycleGridLayout):
    icon_active = StringProperty()
    icon_inactive_color = StringProperty()
    def __init__(self, **kwargs):
        super().__init__(**kwargs)
