"index out of range" error about websockify HOT 3 CLOSED

Well, I've made a bit of progress. By putting in simple debug statements, I've been able to track it down to how websocket.do_handshake handles the incoming handshake. Apparently the incoming handshake is sometimes just an empty array of bytes, but the way the script checks to see if it's empty is to compare it to an empty string. I don't know under what circumstances that check is appropriate, but it doesn't seem to be working as intended on Python 3.2 on Windows. So I modified it from this:

    handshake = sock.recv(1024, socket.MSG_PEEK)
    if handshake == "" 
        raise self.EClose("ignoring empty handshake")

To this:

    handshake = sock.recv(1024, socket.MSG_PEEK)
    if handshake == "" or len(handshake) == 0:
        raise self.EClose("ignoring empty handshake")

That seems to be the appropriate intent of the code, at any rate. But I'm still scratching my head as to why the handshake is empty in the first place.

Interesting. I can't seem to get this to happen with IE or Firefox, just with Chrome. I'm using this with your noVNC library. Any idea why Chrome might handle this stuff different than IE or FF?

Also, if shut down Chrome and reload it, the error still happens. But if I shut down Chrome, connect with IE or FF, then shut those down, and then reconnect with Chrome, it works. Very odd.
