Well, I found the reason for my HTTP 500. It was not related to
Shibboleth at all, it was false direction I was looking for solution.
For the record, the problem was with to short buffer for uwsgi, so the
request was forwarded from properly working Shibboleth to uwsgi proxy,
but uwsgi dropped it and it never reached django app.

If that isn't the problem, then the IdP is apparently broken.

If the metadata in the IdP were fouled up such that the POST endpoint were associated with the artifact binding, I suppose that's a possible explanation, but this is all just speculation and there's no obvious reason that would happen.
