If you create a file whose filename is a double quotation mark and try to delete it in dired-mode, and if you say yes to the questions, the entire directory is deleted.

out <at> themovies:~% mkdir test
out <at> themovies:~% cd test
out <at> themovies:~/test% touch \"\"

Now in emacs dired-mode remove the file ""

  /home/out/test:
  total used in directory 24 available 263498424
  drwxr-xr-x   2 out out  4096 2008-09-04 08:28 .
  drwxr-xr-x 133 out out 20480 2008-09-04 08:28 ..
D -rw-r--r--   1 out out     0 2008-09-04 08:28 ""

Delete  (yes or no) yes
Recursive delete of ? (yes or no) yes
Killed dired buffer of , too (y or n) y

Instead of just removing the file, the entire directory /home/out/test is deleted.
