Related to #5354, entries in core_graveyard don't return a serializable actor. Instead, I get something like below in server logs when trying to pull from the inbox.

TypeError: <LocalUser #5 verified user "machalus"> is not JSON serializable

As a temporary hack, I hardcoded the graveyard actor as shown below. After doing so, pumpa finally was able to pull my inbox and load media and comments.

Entries in core__graveyard don't return a serializable JSON timestamp, resulting in failures of pump clients. The below patch addresses this issue.

There is a problem with old references to the "user" property on the OAuth models. This happened ever since the commit where I changed the user/creator/publisher/uploader all to the "actor" property.

This was reported to me in IRC by ayleph.
