Hi

I have following use case:

I want to sync from one pulp env to another pulp env.
So sync process is pulp#1->crane#1 -> pulp#2

However I got following error, when I was trying to perform the sync:

"traceback": "Traceback (most recent call last):\n  File \"/usr/lib/python2.6/site-packages/celery-3.1.16-py2.6.egg/celery/app/trace.py\", line 240, in trace_task\n    R = retval = fun(*args, **kwargs)\n  File \"/home/brq/jluza/rcm-pulp/server/pulp/server/async/tasks.py\", line 328, in __call__\n    return super(Task, self).__call__(*args, **kwargs)\n  File \"/usr/lib/python2.6/site-packages/celery-3.1.16-py2.6.egg/celery/app/trace.py\", line 437, in __protected_call__\n    return self.run(*args, **kwargs)\n  File \"/home/brq/jluza/rcm-pulp/server/pulp/server/managers/repo/sync.py\", line 110, in sync\n    call_config)\n  File \"/home/brq/jluza/rcm-pulp/server/pulp/server/managers/repo/sync.py\", line 164, in _do_sync\n    sync_report = sync_repo(transfer_repo, conduit, call_config)\n  File \"/home/brq/jluza/rcm-pulp/server/pulp/server/async/tasks.py\", line 483, in wrap_f\n    return f(*args, **kwargs)\n  File \"/home/brq/jluza/pulp_docker/plugins/pulp_docker/plugins/importers/importer.py\", line 94, in sync_repo\n    return self.sync_step.sync()\n  File \"/home/brq/jluza/pulp_docker/plugins/pulp_docker/plugins/importers/sync.py\", line 103, in sync\n    self.process_lifecycle()\n  File \"/home/brq/jluza/rcm-pulp/server/pulp/plugins/util/publish_step.py\", line 503, in process_lifecycle\n    super(PluginStep, self).process_lifecycle()\n  File \"/home/brq/jluza/rcm-pulp/server/pulp/plugins/util/publish_step.py\", line 127, in process_lifecycle\n    step.process()\n  File \"/home/brq/jluza/rcm-pulp/server/pulp/plugins/util/publish_step.py\", line 204, in process\n    self._process_block()\n  File \"/home/brq/jluza/rcm-pulp/server/pulp/plugins/util/publish_step.py\", line 246, in _process_block\n    self.process_main()\n  File \"/home/brq/jluza/pulp_docker/plugins/pulp_docker/plugins/importers/sync.py\", line 192, in process_main\n    available_tags = self.parent.parent.index_repository.get_tags()\n  File \"/home/brq/jluza/pulp_docker/plugins/pulp_docker/plugins/registry.py\", line 332, in get_tags\n    return json.loads(tags)['tags']\nTypeError: list indices must be integers, not str\n",

So I've investigated a bit and found out following difference between official v2 registry and crane:
this is what I get from official v2 registry:

curl -X GET http://rcm-img-docker01.build.eng.bos.redhat.com:5000/v2/jluza/rsyslog/tags/list
{"name":"jluza/rsyslog","tags":["latest"]}

And this is what I get from crane:
curl --insecure -X GET https://rcm-pulp-01-dev.app.eng.bos.redhat.com:5000/v2/docker/rsyslog/tags/list
Redirecting...

and after redirection to:
curl --insecure -X GET https://rcm-pulp-01-dev.app.eng.bos.redhat.com/pulp/docker/v2/docker-rsyslog/tags/list
[]

^ problem isn't in empty tag, repository actually doesn't have any tags, but in output format
