The cause of this problem is that serf uses chunked encoding, a HTTP/1.1
feature that Squid doesn't support:

While adding HTTP/1.0 fallback in serf has been discussed, no one is
working on it.

There are two workarounds:
- use ra_neon instead of ra_serf.
- switch from squid to a HTTP/1.1 proxy, like apache+mod_proxy.

I've updated serf issue 28 at
http://code.google.com/p/serf/issues/detail?id=28 to keep track of this
