Error when changing ManyToManyField referencing "self" with raw_id_admin

[dart@…]

When a model field is defined as follows:

subcomponents = models.ManyToManyField("self", blank=True, null=True,

symmetrical=False,
#raw_id_admin=True, # <- Django bug activated: raw on "self" broken
)

(with the comment removed) the admin interface will raise an ObjectNotFound exception when you edit an object of this type (and you don't have to change this particular field).

I narrowed it down through trial-and-error to that combination of parameters.

Appears to be a duplicate of #1816; fix for raw_id_admin was added in #3858/#3859.
