Yes.

I was using libssh2 1.2.4; testing using the latest git openssh HEAD
(1.2.8_DEV) still exhibits the problem.

Thanks, that's where I'm focussing my attention at the moment; in that
function conn->waitfor is set to 0 after switching to the SSH_STOP
state.

I've attached a sample file that reproduces the problem; it logins to
localhost using 'key.pub' and 'key.prv' in the local directory, and
attempts to upload a file to /tmp/test.txt. If you want to try running
it, just adjust the username and add the relevant keys. Also attached
is the output when it runs on my machine (note that recent version of
libssh & libcurl).

I'll continue to attempt to track down the source of the problem.

Cheers,
Henry
