[Luis Boullosa <1309025@xxxxxxxxxxxxxxxxxx>]

The problem has arisen again in my system when updating to systemd-
services 204-5ubuntu20.5.

I downgraded to the 204-5ubuntu20.4 version and the error disappeared,
so I guess the latest version is provoking the error now.

Title:
  systemd-logind assert failure: cgmanager-client.c:6322: Assertion
  failed in cgmanager_list_children_sync: proxy != NULL

Status in “systemd” package in Ubuntu:
  Fix Released
Status in “systemd” source package in Trusty:
  Fix Released
Status in “systemd” source package in Utopic:
  Fix Released

Bug description:
  SRU:

  Rationale: systemd-logind randomly crashes on random systems, usually
  with a similar traceback or most commonly with a corrupted one. We've
  identified a few problems in the patch, most of which can account for
  the symptoms people have seen and all of which being obviously correct
  bugfixes.

  Testcase: Get the fixes into utopic and trusty-proposed, wait for a
  week for new reports (here and on errors.ubuntu.com), if none were
  reported, push to -updates. While we know what we've fixed, actually
  reproducing the bug in the wild is notoriously difficult, we attempted
  various kind of stress tests over the past 2 months without much
  luck...

  Regression potential: All the fixes are very simple, very targeted and
  pretty obvious, so if we do end up breaking something else as the
  result of that, it's most likely another bug that was hidden behind
  incorrect behaviour. Any such bug should be easy to deal with or we
  can always revert to the current state (better the devil you know).

  
  === Original bug report ===
  Occurred after a dist-upgrade, reboot and logging in.
