Adam Kocoloski commented on COUCHDB-193:
----------------------------------------

Hah, now I see what's happening on trunk -- when the target tries to save the _local doc it fails as a conflict (because the source has already saved it).  Then I try to turn the string <<"Invalid rev format">> into a revision and everything crashes.

Perhaps couch_rep_httpc should just throw an exception if it encounters a conflict.

> I initiated by error a replication to the local machine in a totally stupid fashion. Basically I did something like this (using python-couchdb):
> src_server = couchdb.client.Server('http://localhost:5984')
> src_server.resource.post('_replicate', {'source': dbname, 'target': 'http://localhost:5984/%s' % dbname})
> This resulted in the following strange log entries. The strange thing is, it pushed the server in a "strange" state, where I even wasn't able to create new databases.
