libur-perl: test failures in t/URT/t/21b_load_observer_autosubclass.t

[gregoa]

We have the following bug reported to the Debian package of UR, c.f.
https://bugs.debian.org/951463

It doesn't seem to be a bug in the packaging, so you may want to take
a look. Thanks!

Source: libur-perl
Version: 0.470+ds-1
Severity: serious
Tags: upstream ftbfs sid bullseye
Justification: fails to build from source

libur-perl started failing its testsuite a few weeks ago. This can be
seen on https://ci.debian.net/packages/libu/libur-perl/ and
(hopefully soon, when my smoker's test appears) on
http://matrix.cpantesters.org/?dist=UR%200.47;os=linux;perl=5.30.1;reports=1
and also locally:

Leftover objects in subordinate iterator for URT::Employee.  This shouldn't happen, but it's not fatal... at t/URT/t/21b_load_observer_autosubclass.t line 68.








Cannot change read-only property person_id for class URT::Person!  Failed to update 2 property: person_id from 1 to 2 at t/URT/t/21b_load_observer_autosubclass.t line 98.

Looking at potentially related changes in Debian in the last weeks I
found an upgrade of sqlite3 from 3.30.1 to 3.31.1.

1. github ('s markdown) ate half of the error message; original at https://bugs.debian.org/951463

2. the cpan smoker report (with this and an additional error which might be a local issue) has arrived:

This was fixed in Debian with the upload of sqlite3 3.31.1-4 which includes a backported upstream patch:
