I believe I've got the same bug. I'm on an older dell dimension, and I just installed the Beta on it, then updated today. I get to the gdm screen, then no further, I get a black or tan screen and either a cursor or spinner and thats it. I've got the same two gnome-wm messages in daemon.log. Heres the output of that command:
