Just to be clear, since you said 'decrypting fine':  if you read the
files, they will decrypt fine.  It is only if you append to the file
immediately after mount, and the file is more than one block in size
and not an exact multiple of blocksize (iirc).

If you did mean using append, then that is interesting, bc I've never
had it fail to corrupt a file :)  (or is that :( ).
