GTK problems with FC2

[Jason Charles Pinkney]

Dear Redhatters,

I upgraded my RH 7.3 to FC2 today.
I think I have Xorg working because I
can get a black screen with an "X" after
I do an "Xorg " command.  And the X moves with
my mouse.

But when I do "startx" I get:
    /usr/bin/gnome-session: error while loading shared libraries: 
/usr/lib/libgtk-x11-2.0.so.0:
    undefined symbol: g_type_class_add_private

I've google'd the above but havn't found the solution.
The usual recommendation for such errors is to try
re-installing the program.
When I do
# rpm -q --whatprovides libgtk-x11-2.0.so
I get
    no packages provides libgtk-x11-2.0.so

Other sources said that gtk2-2.4.0-1.i386 (among others) should provide
the above library.  So I've tried reinstalling gtk2--- like so:
# rpm -ivh --force gtk2-2.4.0-1.i386.rpm
  /etc/security/selinux/file_contexts: No such file or directory 
  warning: gtk2-2.4.0-1.i386: V3 DSA signature: NOKEY, Key ID 4f2a6f2d
  g_module_open() failed for /usr/lib/gtk-2.0/2.4.0/loaders/
  svg_loader.so: /usr/lib/librsvg-2.so.2: undefined symbol: 
g_strsplit_set

Should I try ftping a new gtk rpm in case the one on my CD is flawed?
(It passed the error checking.)

Any suggestiongs?

thanks much,
Jason
