Some additional observations:
Browsing the bug list archive (which I probably should have done before
posting) I noticed that the support for Atari disks is implemented as a
patch on top of version 3.2
(http://lists.gnu.org/archive/html/bug-parted/2016-12/msg00004.html). No
wonder I could not find the term 'atari' in the parted 3.2 source :)
Looks like the function atari_probe may be fuddled by some coincidence?

Apparently, the version of parted in the Clonezilla distribution (and of
partedlib used in gparted) is patched (parted --version reports 3.2).
I don't have a full Linux system at hand so I can't compile from source
& depend on binary distributions.
