X failures after 20100921 rawhide update or gtk* failures?

[Clyde E. Kunkel]

On rawhide after 20100921 updates X won't start
and have to boot to runlevel 3 to get to a terminal. Then after startx I 
see the following msg and the server exits:

/usr/bin/gnome-session: symbol lookup error: /usr/bin/gnome-session: 
undefined symbol: gdk_display

Would this be a result of one of the following updates since no errors 
in the Xorg log?
