Did you try to choose the opton "-fsck-y" (or -fsck-src-part-y for older version of Clonezilla live) when saving an image?

  Yes, I checked the filesystem with the clonezilla option and also before
  cloning with e2fsck -f. The filesystem was clean.
  Even if the partition was fresh formatted with no data on it, this error
  remains.

Could you please tell us in detail how you create that Ext4 file system? On which verson of GNU/Linux, and how you create that. We'd like to reproduce the issue here, and if it's reproducible, it could be fixed.
Thanks.

  I do not own this disk and notebook any more but because of the very new
  hardware it was necessary to install a Debian jessie backports kernel
  linux-image-4.6.0-0.bpo.1-amd64 (4.6.3-1~bpo8+1)
  
  I tried 2 methods to create the ext4 filesystem, both with the same result:
  
  mkfs.ext4 /dev/sda1
  and
  mkfs.ext4 -E lazy_itable_init=0,lazy_journal_init=0 /dev/sda1

This is weird. I just could not reproduce this issue here. Attached you can find the results about formating /dev/sda1 as ext4 and saving it as an image successfully.
Which version of mkfs.ext4 did you use?

  Hello Steven,
  
  thanks for testing.
  As I'm not able to provide further details any more and because you
  cannot reproduce this behavior my bug report may be closed.
