Comment 24 for bug 198646

Either savannah changed their system to not include Content-type more than once, *or* it worked because you happened to have a fetch that didn't need multiple ranges. (eg. bytes = 10-60, rather than bytes = 10-20,50-60. In the former case, we don't get a multipart response, so we don't receive multiple Content-type results.)

Ultimately vila or lifeless are the ones who would know the spec, to know whether Savannah is wrong for including 2 Content-Type fields, or if urllib and pycurl are wrong for failing to parse a boundary string under these circumstances.
