This bug was fixed in the package mc - 3:4.8.1-2ubuntu1

---------------
mc (3:4.8.1-2ubuntu1) precise; urgency=low

  * Sync from debian testing (LP: #905610, LP: #314614, LP: #410031,
      LP: #562361, LP: #632816, LP: #713630, LP: #770673, LP: #837163)
  * Added Pre-Depends for dpkg-maintscript-helper availability

mc (3:4.8.1-2) unstable; urgency=low

  * Build-Depends are updated: 'bison' moved to build-deps;
    architecture wildcard replaced silly "type-handling | not+linux-gnu"
    (Closes: #587875 N:"Please remove type-handling dependency")
  * new patch to increase maximum file size for mcedit to 128 MiB
    (Closes: #369565 W:"mcedit: wishing a bigger file size limit")
    Thanks to Daniele Giacomini.
  * new patch to disable "Return does autoindent" by default in mcedit
    (Closes: #570502 N:"mcedit: adding extra spaces when pasting a text
     preceded by spaces")
    (Closes: #575711 N:"pasting extra tabs, AGAIN")
  * added mc.NEWS file with notes about important changes in this release
    (Closes: #661435 W:"lynx-like motion is lost during upgrade to 4.8.1")
  * added symlinks to all scripts in /usr/lib/mc for backward compatibility
  * new patch to correct path to scripts in man page
    (Closes: #661481 N:"Acknowledgement mc: /usr/share/mc/bin/mc.sh missing")
  * 'unzip' added to build-deps to set proper zip mode at build-time;
    'unzip' moved to Recommends from Suggests.
    (Closes: #661467 N:"mc: zip file browsing broken")
  * Recommends 'perl' and 'unzip' instead of Suggests
  * dropped old 20_wrong_path_to_wrappers.patch, which was breaking
    correct path to wrappers (note the precisely chosen file name ;)
  * corrected and properly annotated 09_uzip_broken_528239.patch

mc (3:4.8.1-1) unstable; urgency=low

  * New upstream release [December 2011]
    (Closes: #618542 N:"please follow upstream progress")
    (Closes: #528331 N:"[VFS] utar is unable to open .tar files")
    (Closes: #626287 N:"SHIFT+F6 should open rename dialog")
    (Closes: #609489 I:"If <F4> is pressed ~/.mc/cedit/Syntax is missing")
    (Closes: #606331 I:"regression: panel configuration on startup;
     view search configuration")
    (Closes: #567119 I:"mcedit ignores editnormal in MC_COLOR_TABLE")
    (Closes: #587372 N:"fish does not preserve modification time when
     copying files to remote host")
    (Closes: #592396 N:"file rename (F6) with non-usual characters failed")
    (Closes: #525146 N:"mc hangs when copying multiple files from ftp")
    (Closes: #574761 N:" [VFS] internal tar considers files containig
     '@' as directories.")
    (Closes: #584687 N:"mc/fish segfaults when remote copy/move appends
     to existing file")
    (Closes: #619092 W:"Wishlist: mc to open ISO files")
    (Closes: #602857 M:"use 7zr for generic .7z archives if available")
    (Closes: #61987 W:"total ETA wanted")

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

Status in “mc” package in Ubuntu:
  Fix Released

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.                                                                                                                 [^]
