As per request from bug #1184262, this is a new report, along with dbus
(to be attached)

ProblemType: Bug
DistroRelease: Ubuntu 13.10
Package: systemd-services 204-0ubuntu19
Uname: Linux 3.12.0-custom x86_64
ApportVersion: 2.12.5-0ubuntu2.1
Architecture: amd64
Date: Sun Nov 17 20:24:41 2013
MarkForUpload: True
SourcePackage: systemd
UpgradeStatus: Upgraded to saucy on 2013-10-17 (31 days ago)

SRU INFORMATION:
FIX: https://github.com/desrt/systemd-shim/commit/9e1ebe3ab (in trusty already)

Regression potential: Low. Flushing the session bus was introduced in
version 4 and is obviously bogus as in a system D-BUS service there is
no session bus. This causes lots of confusing error messages and
unnecessary overhead like trying to start dbus-launch. Flushing the
system bus is low-risk, in most cases it's a no-op and it would
otherwise prevent losing signals after waking up. No known regressions.

TEST CASE: Run several suspend/resume cycles with the lid, session
indicator menu, and verify that the network comes back up. It is known
that this fix is necessary but not sufficient, so it is not expected to
fix all cases. But it should not make things worse, so if network now
does not come up any more on a machine where it previously worked this
would count as failure/regression.
