Deleting source db in continuous filtered replication crashes couchdb and prevents restart

Steps to reproduce:

curl -X PUT http://user:pass@localhost:5984/dba
curl -X PUT http://user:pass@localhost:5984/dbb
curl -X PUT http://user:pass@localhost:5984/dba/_design/testapp -d '{"filters": {"rep_filter": "function(doc, req)

{return true}

"}}' -H "Content-Type: application/json"
curl -X POST http://user:pass@localhost:5984/_replicator -d '

{"_id": "testrep1", "source": "dba", "target": "http://user:pass@localhost:5984/dbb", "continuous": true, "create_target": true, "filter": "testapp/rep_filter"}

' -H "Content-Type: application/json"

1. wait long enough for first replication checkpoint
   sleep 10
   curl -X DELETE http://user:pass@localhost:5984/dba

At this point couch crashes and can't be restarted.

Maybe fixed in 1.1.1 by patch in above issue, but I don't have access to confirm.
