Can you also show us the headers the server replied? With -i or "-D -".

-1 is just an internal for "unknown size" which seems to indicate that there
was no Content-Length: in the reply headers.

Without a known size, the server must close the connection to signal to the
client when the transfer is done and this looks as if curl perhaps doesn't
really notice the closure.

7.9.3 has brand new non-blocking sockets internally, which might have
introduced a few problems like this. If you need this working really fast,
I'd suggest you downgrade and try 7.9.2.

Of course, we still need to fix 7.9.3 if this truly is a bug.
