sftp stat error - LIBSSH2_ERROR_SFTP_PROTOCOL

Hi,

I am getting sftp stat error -31.

I am using Solaris 10/GCC/libssh2 1.2.5.

This is a brief rundown of the code:
1. Create socket
2. Create ssh2 session
   session = libssh2_session_init();
   if (status=libssh2_session_startup(session, sock)) {
     fprintf(stderr, "Failure establishing SSH session - %d\n",status);
     exit(1);
   }
3. User authentication ... suceeds
   userauthlist = libssh2_userauth_list(session, username, strlen(username));
   if (strstr(userauthlist, "password") != NULL) {
     auth_pw |= 1;
   }
   if (auth_pw & 1) {
      /* Authenticate via password */
      status=libssh2_userauth_password(session, username, password);
      if (status==0) {
          fprintf(stderr,"\tAuthentication by password succeeded.\n");
          return(0);
      }
   }
4. sftp stat
   char buf[]="/tmp/myfile";
   sftp_session = libssh2_sftp_init(session);

   if (!sftp_session) {
     status=libssh2_session_last_errno(session);
     fprintf(stderr, "Unable to init SFTP session - %d\n",status);
     return(1);
   }
   status=libssh2_sftp_stat(sftp_session,buf,&fileinfo);

I'm getting error -31 (LIBSSH2_ERROR_SFTP_PROTOCOL) and on calling
libssh2_sftp_last_error(sftp_session, I get error 2.

I put sshd on the target machine into debug mode (sshd -d -d -d) and this is what I get:
debug3: fd 4 is not O_NONBLOCK
debug1: Server will not fork when running in debugging mode.
debug3: send_rexec_state: entering fd = 7 config len 321
debug3: ssh_msg_send: type 0
debug3: send_rexec_state: done
debug1: rexec start in 4 out 4 newsock 4 pipe -1 sock 7

Can you please suggest what is wrong? The same code worked OK under Redhat and
libssh2 version libssh2-1.1.
