Subject: [Rd] [R] can't load just saved R object "ReadItem: unknown type
	65"

According to the logs nothing at all has changed in the serialization
code in a month and nothing of consequence for much longer than that.
To track this down we will need a complete, reproducible, and
preferably minimal example.
