I am looking to disconnect the `post_init` signal in a management command
due to exceptions it raises in my scenario. My disconnect looks like
this:
{{{#!python
signals.post_init.disconnect(ImageField.update_dimension_fields,
sender=Bug)
}}}
If I'm doing something wrong, I'd love to know what.
Digging in a bit, it's caused by the fact that the lookup key generated in
the `.connect()` at
https://github.com/django/django/blob/stable/1.11.x/django/dispatch/dispatcher.py#L105
differs from the one generated in `.disconnect()` at
https://github.com/django/django/blob/stable/1.11.x/django/dispatch/dispatcher.py#L153
Maybe related to #22657. See the attached project to reproduce.
