I can reproduce this. I added a "sleep 5" to a pm-utils sleep.5 script.
When I run systemd-shim in the foreground in my session, I get this
output after resuming:
14:39:18 O: GDBus-debug:Address: In g_dbus_address_get_for_bus_sync() for bus
type 'session'

and indeed I see a new dbus daemon:

//bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session
If I run the shim under env -u DISPLAY (as it would when being D-BUS
activated), I get the same D-BUS errors as in the logs of the reporters.
