Neutron API - problem parsing semi-colon in X-Headers Red Hat OpenStack Platform 14

In the current state when a GET request is sent with Accept: application/json; charset=utf-8, one receives the following Neutron error:

$ curl -s -H "Accept: application/json; charset=utf-8" -H "X-Auth-Token: $OS_TOKEN" "http://191.`68.123.10:9696/v2.0/networks" | python -mjson.tool
{
    "NeutronError": {
        "detail": "",
        "message": "The server could not comply with the request since it is either malformed or otherwise incorrect.",
        "type": "HTTPNotAcceptable"
    }
}

This worked on previous releases (ie. 12 & 13)
