Huh, weird. Do you have any unusual/local/non-standard configuration in
/etc/dbus-1/system.conf, /etc/dbus-1/system.d/*.conf,
/etc/dbus-1/system-local.conf or /usr/share/dbus-1/system.d/*.conf?

I don't suppose you have a core or backtrace for this, from corekeeper
or systemd-coredump or similar?

Seems plausible. Given that root cause, the rest of your log looks like
the expected cascade of errors as everything else falls off the bus.
