client doesn't output proper json

When using the reddwarf CLI tools, we have issues with some output not being valid json where it would be very useful - specifically with the reddwarf-mgmt-cli:

1) reddwarf-mgmt-cli instance list | python -m json.tool
Extra data: line 41 column 1 - line 702757 column 1 (char 1174 - 20586647)
== example output ==
{
    "created": "2012-07-26T21:19:39",
    "deleted": true,
 ...... omitted....
    "volume": {
        "size": 3
    }
} <----------------------- NO COMMA
{
    "created": "2012-11-20T00:07:42",
    "deleted": true,
 ...... omitted....
    "updated": "2012-11-20T00:30:55",
    "volume": {
        "size": 5
    }
}

2) reddwarf-mgmt-cli host list | python -m json.tool
Extra data: line 5 column 1 - line 97 column 1 (char 50 - 1220)
== example output ==
{
    "instanceCount": 14,
    "name": "db-n24"
} <----------------------- NO COMMA
{
    "instanceCount": 14,
    "name": "db-n05"
}

So far, that's the only two that I found. Some commands don't output json at all - i.e. instance delete --id <>
