Deleted document in _changes is missing

[Ian Goodacre]

Hi all,

I am running CouchDB 1.6.1 on Linux.
I have a database that has many deleted documents and I am able to 
retrieve most of these but there are a few that I am unable to retrieve. 
When I attempt to retrieve these, I get 404 with error 'not_found' and 
reason 'missing'.

I would like to understand why these few documents are different - why 
am I unable to retrieve these deleted documents?

For example, _changes response includes:

    {
      "deleted": true,
      "changes": [
        {
          "rev": "2-338d783957e141566caf3662cc0726bb"
        }
      ],
      "id": "assets_0000245",
      "seq": 2355
    },


When I attempt to retrieve this with:

http://localhost:5984/dcm_assets_tp/assets_0000245?rev=2-338d783957e141566caf3662cc0726bb

I get a 404 response.

I am expecting to get the deleted document, even it if only contains 
_id, _rev and _deleted.

Also, I don't understand the response to

curl --noproxy '*' -X GET 
'http://localhost:5984/dcm_assets_tp/assets_0000245?open_revs=all'

which is

--a341c8902ae323bd6ea7d938bc0c2ac5--

And I get the same in response to

http://localhost:5984/dcm_assets_tp/assets_0000245?revs=true&open_revs=all

But, if I add -H 'Accept: application/json' then I get an empty array ([]):

curl --noproxy '*' -X GET -H 'Accept: application/json' 
'http://localhost:5984/dcm_assets_tp/assets_0000245?open_revs=all'


I must be misunderstanding something (or a lot of things). Any help would be 
appreciated.

Regards,
Ian
