Unable to Replicate from ACRA to localhost CouchDB

[ghost]

I'm using CouchDB version 1.6.1 and just want to try replicate from Acra. using Replicator menu with parameters :
from Remote Database: http://get.acralyzer.com/distrib-acra-storage
to Local Database: acra-myapp

But, the process just running and not finish. and then i got message from browser console :

Failed to load resource: the server responded with a status of 500 (Internal Server Error)
jquery.couch.js:1016 Uncaught Replication failed: undefined

I had the same problem in Ubuntu 14 and CouchDB 1.6.1. After install couchapp (https://github.com/couchapp/couchapp) and dependencies I'm able to replicate from Acra.
