Bug#1031725: unblock: accountsservice/22.08.8-6

[Simon McVittie]

Package: release.debian.org
Severity: normal
User: release.debian.org at packages.debian.org
Usertags: unblock
X-Debbugs-Cc: accountsservice at packages.debian.org
Control: affects -1 + src:accountsservice

accountsservice could benefit from some appropriate age-days to get it
into testing a bit sooner. It's currently at 3 of 10 days.

(Do you want requests like this for important/RC bug fixes during soft
freeze in general, or should maintainers prefer to wait 10 days and hope
that manual intervention isn't needed?)

[ Reason ]
Fixes a regression introduced while fixing previous RC bugs.

[ Impact ]
If not accepted, accounts-daemon crashes with an assertion failure on
systems where /etc/shadow doesn't exist (pwunconv or shadowconfig off),
which is inadvisable but at least partially supported. This leads to
gdm and probably other login managers not starting, preventing login.
(#1031309)

This is a regression caused by my previous fix for #1030262, which is
already in testing. At the time of fixing #1030262 it hadn't occurred
to me that a missing /etc/shadow was something that could happen on a
supportable system.

[ Tests ]
The scenario with the crash was manually tested in a bookworm GNOME VM. It
seemed too rare and weird to add an automated test, but the automated test
added while fixing #1030262 and #1030253 still passes in this version.

[ Risks ]
The service is high-visibility and security-sensitive, but the change
is straightforward (allowing a hash table to be NULL) and was already
accepted upstream.

[ Checklist ]
  [x] all changes are documented in the d/changelog
  [x] I reviewed all changes and I approve them
  [x] attach debdiff against the package in testing
