Title:
  mtools truncates short filenames in a way that can cause conflicts

Status in “mtools” package in Ubuntu:
  Fix Released
Status in “mtools” source package in Lucid:
  Fix Released
Status in “mtools” source package in Karmic:
  Won't Fix

Bug description:
  Binary package hint: mtools

  On karmic and lucid, the newer version of mtools introduces a
  regression that causes filenames to break. According to the mtools
  documentation (http://mtools.linux.lu/mtools.html#SEC7), long
  filenames beyond eight characters should be truncated down to six
  characters then a tile and number. i.e. thisisatest becomes THISIS~1
  for the short filename.

  This behavior works correctly on 3.9 series mtools releases, but on
  4.0, thisisatest would get truncated to thisisat. A simple testcase to
  this behavior is the following:

  mcasadevall at daybreak:/tmp$ mkdosfs -C test.img 10000
  mkdosfs 3.0.3 (18 May 2009)
  mcasadevall at daybreak:/tmp$ mmd -i test.img libgnomecanvas
  mcasadevall at daybreak:/tmp$ mmd -i test.img libgnome
  Long file name "libgnome" already exists.
  a)utorename A)utorename-all r)ename R)ename-all 
  s)kip S)kip-all q)uit (aArRsSq): q
  mcasadevall at daybreak:/tmp$ mdir -i test.img
   Volume in drive : has no label
   Volume Serial Number is 952C-0A14
  Directory for ::/

  libgnome     <DIR>     2009-11-12  13:52  libgnomecanvas
          1 file                    0 bytes
                           10 199 040 bytes free

  
  The attached debdiff corrects this behavior by having mtools properly truncate the short filename to libgno~1 in that case.
