eBay API returns JSON when text/plain is specified in header

Question

I'm looking for some perspective. I'm entirely new to API programming. I've found that calling eBay's GeteBayTime method is correctly returning JSON but with a header of text/plain;charset=utf-8, not application/json. Is this an eBay bug, just average API weirdness, acceptable in some way or what? Could it be an error on my part? I'm using C++ Rest SDK for client API access.

The solution, for those who face the same issue, is to change the response header using set_content_type():

    if (response.status_code() == status_codes::OK)
    {
        response.headers().set_content_type(L"application/json");
        return response.extract_json();
    }

The actual request uses:

http://open.api.sandbox.ebay.com/shopping?callname=GeteBayTime&responseencoding=JSON&appid=<my appid>&siteid=0&version=713

I received a good response at https://casablanca.codeplex.com/discussions/470633. I believe there's more room for discussion. Until then, this will be the standing answer.
