Hi Wichert,

  My working machine is woody (dpkg 1.9.21), but I also tested in
another machine (sid, dpkg 1.10.9) and it also gives the same segfault.

  md5sum returns the following error:
   error processing a/b: failed in buffer_read(fd): mdfile: Is a directory
   Segmentation fault

  Please, follow these steps and check if it segfaults...

      cd /tmp/
      mkdir a
      echo "test" > a/b
      mkdir c
      mkdir c/a
      mkdir c/a/b
      md5sum a/b > /tmp/md5
      cd c
      md5sum -c /tmp/md5

  Thanks in advance,
    Pedro
