path.join error with paramiko/paramiko_scp on get_r("/")

[DipSwitch]

When you call scp.get_r("/") the line below would generate an error.

paramiko/paramiko_scp:~364 change :

        try:
            mode = int(parts[0], 8)
            path = os.path.join(self._recv_dir, parts[2])
        except:
            self.channel.send('\x01')

To:

        try:
            mode = int(parts[0], 8)
            if (len(parts) >= 3):
                path = os.path.join(self._recv_dir, parts[2])
            else:
                path = self._recv_dir;
        except:
            self.channel.send('\x01')
