listen_xxx functions dont allow objetcs as custom kwargs

[mmattel]

What happened?

I have a setup where an app includes another module. To make the app slim, all major functions are located in that included module. Therefore I handover self as function call parameter and is used as iself in the modules code. This works flawless like for logging. But it breaks when using listeners with custom arguments (kwargs) at the end, see the examples:

Docs does not state any limitations with respect to the type of the value of the named argument, therefore this is either a bug or the docs need to be more precise about the value types allowed.

Version

Installation type

When using an object as kwarg value, this error raises:
