I think I have just bumped into the same problem as reported by http://www.libssh2.org/mail/libssh2-devel-archive-2009-06/0032.shtml, at least I am assuming it is the same as this Mailing list entry, I have no way of know what is running on the server I am trying to connect to.
I've done a bit of digging into the RFC's and IETF documents and if this has not yet been fixed I would like to have a go at it, but I have a couple of questions.
The first question is what would be the best way of recovering from the error? Set the window size to the same as the servers' own window?
The second question is detecting the error. The response from the server in this particular case is a disconnect message with a reason of SSH_DISCONNECT_PROTOCOL_ERROR. The message data is just the text of the error message.

[libssh2] 1.686766 Transport: Disconnect(2): Bad window size in WINDOW_ADJUST.(en)
There does not appear to be a standard way of rejecting a window adjust request, so are there any suggestions anyone may have for detecting this response from the server other than looking specifically for the above text (which doesn't seem to be a very clean way of fixing it)?
If I do manage to fix it what is the best way of submitting the fix?
