Comment (by bagder):

 Can you please try to apply a debug patch such as the following to see
 what kind of size libssh2 thinks it is getting:

 {{{
 --- a/src/sftp.c
 +++ b/src/sftp.c
 @@ -205,10 +205,13 @@ sftp_packet_read(LIBSSH2_SFTP *sftp)
          packet_len = _libssh2_ntohu32(sftp->partial_size);
          /* make sure we don't proceed if the packet size is unreasonably
             large */
 - if (packet_len > LIBSSH2_SFTP_PACKET_MAXLEN)
 + if (packet_len > LIBSSH2_SFTP_PACKET_MAXLEN) {
 + fprintf(stderr, "INFO: Got %u bytes packet\n",
 + packet_len);
              return _libssh2_error(session,
                                    LIBSSH2_ERROR_CHANNEL_PACKET_EXCEEDED,
                                    "SFTP packet too large");
 + }

          _libssh2_debug(session, LIBSSH2_TRACE_SFTP,
                         "Data begin - Packet Length: %lu", packet_len);

 }}}
