This is the situation: I'm using a Git commit from fgallery with extra
features I've added locally.  So this is a bad test case for somebody
else since it derives from the official Debian package.  This fgallery
is unchanged since three monthes and

  1. worked until 16. September under testing
  2. stopped working after my upgrade yesterday to libjson-xs-perl
     3.020-1+b1
  3. works again with libjson-xs-perl 3.010-2 (which I needed to
     rebuild since the binary deb on snapshots requires an older
     perl version

The failure is identical to what is described here:

   https://rt.cpan.org/Ticket/Display.html?id=109026

and may be these links lead to an easily reproducible example.

I have some backlog from holidays but I'll try to do my best
if the hints above are not sufficient.

Kind regards
