 The offending patch is: https://gitweb.torproject.org/tor-

 And I think I know what is going on: `nsSocketTransport::SocketHost()` is
 using the host of the nsIProxyInfo if there is any. And per default meek
 is creating an HTTP channel with a nsIProxyInfo which is instructing the
 browser to make a direct connection (type `DIRECT`). Thus, the host is
 empty but is nevertheless selected as the socket host as
 if (mProxyInfo && !mProxyTransparent) {
 is `true`. I guess we should just check that we not only have an
 nsIProxyInfo but a non-empty host as well
 (`nsSocketTransport::SocketPort()` is affected, too). Arthur?

 (dcf - thanks for the logs they were pretty helpful and saved me some time
 :) )
