Well, actually it happened with all xorriso generated images.
The problem is on the side of isoinfo and known since about three
weeks. It has been addressed in xorriso-1.1.0 resp. libisofs-1.1.0.

isoinfo seems to dislike the presence of Rock Ridge NM fields
with directory entries for CURRENT and PARENT.
But RRIP 1.10 and 1.12 describe these fields explicitely.
In 1.10 they may contain any name. 1.12 prescribes empty names.
For details see comments in

Meanwhile libisofs omits the NM fields if the old RRIP 1.10
is chosen, which is the default with xorriso.
isoinfo then shows '.' and '..'.

One would have to upgrade libisofs resp. GNU xorriso on the machines
which produce the ISO images.
libisofs-1.1.0 is in Debian "sid".

Have a nice day :)
