Title:
  mc crashes when trying to move file to nonexistent directory in FTP

Status in “mc” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: mc

  To reproduce follow these steps:
  1.  Start mc:
  $ mc
  2. Open ftp directory in mc by entering in command line:
  cd /#ftp:l33t at 1337ftp.co.cc:l33thackersFTW at 1337ftp.co.cc
  (any FTP server with write access should be acceptable, this is first address I found in Internet:
  http://www.l33thackers.com/Thread-Public-FTP-for-l33thackers so this is NOT private information.)
  3. Navigate to any file in FTP directory, press <F6> to start moving, enter target directory name that doesn't exists, like "test14323/"

  Expected behavior:
  mc should report that file can not be moved.

  Observed behavior:
  mc crashes with SIGSEGV:

  ftpfs: CWD failed.
  Program received signal SIGSEGV, Segmentation fault.                                                                                                                 [^]
