Many thanks for the reply now, is much appreciated to see were we
stand. Yes I can perfectly understand the reasoning. the change is now
pending for 3.16.51-4 (or any later interation via a point release of
jessie), so if it happens to you to not have updated to stretch yet
and see your issue resolved as well we can close the second bug.
Regards,
Salvatore
