Adding export DBUS_DEBUG_OUTPUT=1 to the params section of /etc/default/dbus resulted in the same errors as before, with system unresponsiveness at the login screen. A hard restart is required to reboot, and I had to recovery console into the config file and remove the option to get my system to work. Looking at my logs, it appears that dbus just doesn't start with that option enabled, either way a few services seem to be freaking out because of it (relevant section in syslog attached).
