>                 URL: https://issues.apache.org/jira/browse/COUCHDB-885
>             Project: CouchDB
>          Issue Type: Bug
>          Components: Database Core
>    Affects Versions: 1.0.1
>         Environment: Mac OSX, Windows XP, Windows 7
>            Reporter: Nikolai Teofilov
>             Fix For: 0.11
>
>
> Step to reproduce the bug:
> 1.  Make database "test" on a remote couchdb server that reside on a different machine! 
> 2.  Create new document:  "http://remote-server:5984/test/doc"
> 3.  Create database "replica"  on the local couchdb  server.
> 4.  Trigger pull replication  http://remote-server:5984/test -> http://localhost:5984/replica
> 5.  Attach a file to the replicated document on the local couchdb server.
> 6.  Trigger push replication http://localhost:5984/replica  -> http://remote-server:5984/test
> The document in the test  database shows one conflict. If instead attachment the document is updated with a new field after the replication no conflict.
> The same sequence shows no conflicts on CouchDB 0.11.
