empty images section in duffle bundle

[sbawaska]

A duffle.json with an images section builds successfully, however, the duffle bundle show does not carry values for the images section. This results in duffle export throwing an error.
sample duffle.json

{
    "name": "kab",
    "version": "0.1.0",
    "description": "A short description of your bundle",
    "keywords": [
        "cnab",
        "kab"
    ],
    "maintainers": [
        {
            "name": "Swapnil Bawaskar",
            "email": "foo@pivotal.io",
            "url": "https://example.com"
        }
    ],
    "invocationImages": {
        "cnab": {
            "name": "cnab",
            "builder": "docker",
            "configuration": {
                "registry": "sbawaska"
            }
        }
    },
    "images": {
        "istio": {
            "description": "istio images",
            "imageType": "docker",
            "image": "docker.io/istio/citadel:1.0.2",
            "digest": "sha256:ca4050c9fed3a2ddcaef32140686613c4110ed728f53262d0a23a7e17da73111"
        }
    },
    "parameters": null,
    "credentials": null
}

After building:

$ duffle bundle show kab
{
    "name": "kab",
    "version": "0.1.0",
    "description": "A short description of your bundle",
    "keywords": [
        "cnab",
        "kab"
    ],
    "maintainers": [
        {
            "name": "Swapnil Bawaskar",
            "email": "foo@pivotal.io",
            "url": "https://example.com"
        }
    ],
    "invocationImages": [
        {
            "imageType": "docker",
            "image": "sbawaska/kab-cnab:37ef8c95617299bffc8ff880e1ec17f5c78ee168",
            "platform": {}
        }
    ],
    "images": {
        "istio": {
            "imageType": "",
            "image": "",
            "platform": {},
            "description": "istio images",
            "refs": null

    },
    "parameters": null,

What is the output of duffle bundle list | grep kab ?

Okay, I just reproduced this locally.

Update: And reproduced on the actions field as well.
