Why do I get an error when creating an instance of FileChooserIconView?

Question

Python

Hello, when creating a FileChooserIconView instance from kivy.uix.filechooser, I get the following error:

Strange though, since everything works in kv

Answer 1

Well, the problem is related to the fact that backup services are running in parallel.
To solve it, you can:
1) Disable this service (Google has examples)
2) Use the filters parameter for this function. So that it ignores the files that cause the error.
