this looks to have been there for a while.

you do a recursive wget, with continue set on an HTTP site.
if there's still data to be retrieved, you get the real content type.
if there's not, you potentially get an html error.
if that happens, wget tries to parse additional urls out of the original file, and will OOM on large binaries.

ugly fix: on continue, try to get from (currentsize-10) which will ensure the content-type header matches the original file.

proper fix: maybe head-request the url to get the content-type from that ?

hth.
