Yes, I am seeing this behavior as well. Coincidentally, or not, I also use GoLive and I also see these EmptyReference items in the .php files.
This happened after an upgrade from 1.5 to 1.5.1.2, when I extracted the new WP 1.5.1.2 files and uploaded them according to the instructions here on this site.
It does seem like GoLive has probably done something to the files but I cannot see what to do.
Thanks.
