Description (last modified by Ronny Vedrilla)

Here's my setup on django 3.0.10:

class MyModel(models.Model):
     pass

@receiver(post_save, sender=MyModel)
@receiver(post_delete, sender=MyModel)
def process_stuff(sender, instance, **kwargs):
    # to some magic
    pass

When I want to disconnect the post_save signal like this:

from django.db.models import signals
signals.post_save.disconnect(
        receiver=process_stuff,
        sender=MyModel,

... it does not work.

If I comment out the second decorator with post_delete, it works.

If I split this up and use two different functions, it works as well.

I posted at StackOverflow (​https://stackoverflow.com/q/64102708/1331671) and in some django groups, but no replies yet.

Seems like a bug to me :(
