Why has yum behavior changed in F9?

[Paolo Galtieri]

Today I installed F9 on an x86_64 laptop which previously was running F8 
and so far I find F9 to be a regression from F8. In F8 when I ran:

  yum -y install gtk2

it would install both the i386 version and the x86_64 version of the 
package. In F9 it only installs the x86_64 version, I have to explicitly 
install the i386 version. Why the regression?

The reason I see this as a problem is if you download the Adobe acrobat 
reader package for Linux from Adobe it is built for i386 and 
consequently will not install unless you install the required i386 
packages. 

Furthermore:

[root at localhost ~]# yum list all gtk+
Loaded plugins: refresh-packagekit
Available Packages
gtk+.i386                                1:1.2.10-61.fc9        
fedora         
gtk+.x86_64                           1:1.2.10-61.fc9        
fedora         

shows both the i386 and the x86_64 versions, but:

yum -y install "gtk+*"

Only installed the x86_64 packages, when I would have expected, via the 
globbing syntax, that  yum would have installed all packages matching gtk+.

So what's going on and how do I force yum to always install both the 
i386 and x86_64 versions of a package?
