New submission from Mathieu Dupuy:
When connecting to a IIS server, it replies that:
Unauthorized Server: Microsoft-IIS/7.5
WWW-Authenticate: Digest
qop="auth",algorithm=MD5-sess,nonce="+Upgraded+v1fe2ba746797cfd974e85f9f6dbdd6e514ec45becd2d8cf0112c764c676ad4a00f98517bb166e467dcad4b942254bd9b71d447e3529c509d2",charset=utf-8,realm="Digest"

which blew python 2.7 utllib2 like this:

k, v = elt.split('=', 1)
ValueError: need more than 1 value to unpack
urllib2 seems to assume that every www-authenticate header value will be a list
of equal-signe-separated tuple.
On python3, the error is different and trigger this
