This means the server didn't send a good-looking final chunk
in the chunked-encoding stream.

wget doesn't see this problem because it speaks HTTP/1.0 and
as you can see, the server responds quite differently in
that case.

I'm sure you can work around this server bug with curl too
by using --http1.0

If you use --trace or snoop on the traffic with ethereal or
similar, I'm pretty sure you'll see that this is a server error.
