Apparently the bug is in the ubuntu packages. If I manually install pycurl,
correctly set the library path, it works with the previous parameters.

using: /usr/local/lib/python3.4/dist-packages/pycurl.cpython-34m.so

pycurl.cpython-34m.so->curl_easy_setopt(0xe41d70, 172, 1, 0) = 0

I don't understand though why the ubuntu version doesn't work with an
identical call.
