Hi,
I experienced a similar problem with libssh2 and I had to recompile it with
the latest libssh2 version present in CVS ( if I remember correctly there
was a bug on channel.c corrected using a workaround, last august).
Try to re-compile it with the latest version and see if it works for you.
Regards,
Antonio
