During the recent months we've worked on SFTP quite significantly, so I would
recommend you to base further testing on curl 7.19.3 with libssh2 1.0 and
nothing earlier.

(You're also using a rather outdated OpenSSL version but I don't think this
causes these particular problems.)

I don't know what that is or what it means, but it looks libssh2-specific so I
suggest you proceed to try a libssh2 example code against that server and if
the problem remains you continue this on the libssh2-devel list!

First, upgrade curl and libssh2. Then if the problem remains, try an libssh2
example code and see if that works. If not, go libssh2-devel as mentioned
above. If the example code does work, build a debug-version of libssh2 and
enable full ssh tracing in libcurl (see the libssh2_trace() call in
lib/ssh.c).
