Comment 1 for bug 2025317

db.applications.find({},{"charm-origin.id":1}).pretty() shows a couple of charms without any charm-origin

e.g.:

{
 "_id" : "3f822b7a-63ed-402d-8b2c-c1f25c3f731d:sysconfig-ctrl",
 "charm-origin" : {
  "id" : ""
 }
}

removing those charms unblocked the upgrade, but those were all subordinates, which we can remove, what if this is a principal charm?
