In the meantime I have tried the "long name" and the "long ID"
properties to directly identify "unplaced" backgrounds. The results are
the same as with the "owner" property:
Both "unplaced" backgrounds -. that have only the stack as its owner -
and backgrounds placed on cards you did not go to before - return the
"stack" as owner or the next object up in the hierarchy.
So the above described workaround is necessary here, too, to find the
real "unplaced" backgrounds.

Any other suggestions what to try else to find directly unplaced

Stephen Messimer´s message below is somewhat related to my question.
I`ll comment only one line of it ("
Specifically how does one "unplace" a grp once it is made?"):

You choose "remove" in the "edit backgrounds" dialog. If the background
you removed is on no other card as well, it is now totally "unplaced", a
sort of free-floating object in the stack.

I am also interested in Jeanne´s answer to the question below concerning
the object hierarchy.
