But isn't deletion of holder already handled?
Also inside loc will be null if it's deleted so that shouldn't hit this check (presumably...)

See the linked PR. They claim that check_holder() can occur after the qdel signal nulled it resulting in it un-nulling it.

I honestly don't get it, datum Destroy should clear any signal preventing this issue - but i guess it's upstream's problem now
