Querying a view on a 4 node cluster gives error "Badarg error in HTTP request"

Steps to reproduce:
1. Create default bucket(1 replica) and 128 vbuckets.
2. Load 1000 json docs or skip loading(reproducible both ways)
3. Add 3 nodes and rebalance in
4. Create a view
curl -v -X PUT -H 'Content-Type: application/json' 'http://Administrator:password@10.3.3.95:8092/default/_design/dev_d1' -d '{"views":{"v3":{"map":"function(doc)

{\nemit(doc._id,doc.n2);\n}

"}}}'

curl -X GET 'http://Administrator:password@10.3.3.95:8092/default/_design/dev_d1/_view/v3?stale=ok'

curl -v -X GET 'http://Administrator:password@10.3.3.95:8092/default/_design/dev_d1/_view/v3?stale=ok'
