The unmounted Private directory should have permissions 500.  This is
set by the ecryptfs-setup-private utility.  Did you manually change
them?  Possibly some other program?

While it is not mounted, run:
 $ chmod 500 ~/Private

See if those permissions stick, and if any more files show up there.

Do you have any idea what is creating x.png.nc?  What application, I
mean?

Bug description:
I am using the latest 8.10.
When the user with a private directory is not logged in, root can have a look in the Private directory and see exactly one file in clear:

lrwxrwxrwx 1 norbert norbert     28 2008-10-15 23:19 THIS DIRECTORY HAS BEEN UNMOUNTED TO PROTECT YOUR DATA --  Run mount.ecryptfs_private to mount again -> /sbin/mount.ecryptfs_private
-rw------- 1 norbert norbert 421581 2008-10-15 22:15 x.png.nc


Here the file x.png.nc is the one. 
This file can be extracted and viewed.

Regarding the nature of this directory, I regard this problem as security relevant.
