Yeah, an ancient bug... just been fixed in F8 to show the arch too for all

The rules haven't changed since the introduction of multilib (rpm 4.0 days 
or so): on multilib systems conflicts on files of same color are swallowed 
when the conflicting packages are installed in the same transaction, but 
when installed in separate transactions conflicts are raised.

Yes it's confusing and inconsistent behavior which I *really* want to get 
rid of. It's just that this is not a simple matter of "fixing rpm" - our 
package set is full of conflicting files. The package set needs fixing, 
otherwise you'll have a very much uninstallable x86_64 (and to slightly 
lesser effect ppc) tree.
