Betamax corrupts some responses

[DeCarabas]

Here's a simple test, which fails on betamax 0.60.0:

from betamax import Betamax
import requests

def test_get_url_image():
    http_session = requests.Session()
    url = 'https://www.crummy.com/software/BeautifulSoup/10.1.jpg'
    expected = http_session.get(url)

    with Betamax(http_session).use_cassette('test_get_url_image'):
        actual = http_session.get(url)

    assert expected.content == actual.content

It fails: actual.content is different than expected.content. I haven't looked very closely to see what's wrong, but something is.

Is this a regression from 0.5.x?

Also that URL isn't working for me. Do you have one that exhibits this behaviour?

Betamax stores response data in JSON. Arbitrary bytes sometimes are able to serialize to JSON which gives the false sense of "working". In this case, when they're deserialized, they're corrupted, as you point out. If you look at our documentation we explain this and how to fix it.
