existing decode file not visible (same error as #550?)

[Javeree]

I observe on one PC running gentoo Linux the same issue as #550 with encfs 1.9.5.
If the decoded file is accessed directly it acts as a normal file. It is correctly encoded, but when one asks to list all files in the decoded directory, it is not visible.

`#Create encfs directories
encfs /mnt/hd/.encfs /mnt/hd/encfs
The directory "/mnt/hd/.encfs/" does not exist. Should it be created? (y,N) y
The directory "/mnt/hd/encfs/" does not exist. Should it be created? (y,N) y
Creating new encrypted volume.
Please choose from one of the following options:
enter "x" for expert configuration mode,
enter "p" for pre-configured paranoia mode,
anything else, or an empty line will select standard mode.
?>

Standard configuration selected.

Configuration finished. The filesystem to be created has
the following properties:
Filesystem cipher: "ssl/aes", version 3:0:2
Filename encoding: "nameio/block", version 4:0:2
Key Size: 192 bits
Block Size: 1024 bytes
Each file contains 8 byte header with unique IV data.
Filenames encoded using IV chaining mode.
File holes passed through to ciphertext.

Now you will need to enter a password for your filesystem.
You will need to remember this password, as there is absolutely
no recovery mechanism. However, the password can be changed
later using encfsctl.
