It occurs to me that the message may be a red herring; neither of the
bug reports seems to suggest that the lack of these objects causes (or
should cause) your babies to get eaten. Can you look through the
boilerplate at https://fedoraproject.org/wiki/How_to_debug_Xorg_problems
and see if any of that helps you get more informative / detailed logs?
