Helm template blows up when trying to use checksums. To reproduce it, simply create a helm chart with "helm create" then edit the deployment.yaml so the spec template contains:
...
template:
metadata:
annotations:
checksum/config: {{ include (print $.Template.BasePath "/deployment.yaml") . | sha256sum }}
...

Try to generate the manifests with: "helm template --output-dir manifests". You will get something like the log attached.
This of course affects any other commands that rely on generating the manifests like "helm install".
