I suspect this is caused by race between systemd realizing that cgroup for a scope
is empty, thus changing its state, and dispatching dbus message coming from
logind where it asks systemd to mark scope as abandoned. I don't think this is a
big deal so we could log this only if debug is on.

To make sure if it is the case can you try to reproduce with systemd and logind
debug turned on. Thanks!
