The 400 errors are logged once client opens a connection but fails 
to send complete request, most commonly - opens a connection and 
closes it without sending anything.  This is not a bug (well, may 
be in your client).  We are considering changing this behaviour 
though, as growing popularity of Chrome makes such log lines 
useless.

In your tests with netcat you are likely failed to sent complete 
request properly (e.g. missed last empty line to mark request 
headers end), which will result in similar error (though in this 
case there will be request logged, i.e. "GET / HTTP/1.1").
