Thanks for reporting this.
What kind of file system are you writing to?

If you execute the following shell commands:

  rm sparse
  dd bs=1 seek=131073 of=sparse
  strace -o tr cp --sparse=always sparse copy

what are the last few system calls (in the file 'tr')?  It'd be nice
to see the pattern, so that we can know what actually failed.
