Dunno if this is the same problem or not, but I often find smart wants to install an i586 package during upgrades.  Running OpenSUSE 11.1.  Running smart 1.2-4.1.

Example: I want to upgrade to the latest OpenOffice.org 3.2 release candidate.  So I do:

smart> install OpenOffice_org

Well.  My local repository deliberately doesn't have i586 packages, so it fails to download that i586 goofball.  If I try to install the RPM's manually, this happens:

Installing packages (1):

This time rpm installs everything (modulo that silly 3.1.1.5 package).

Basically, I don't think smart should *ever* install an ix86 package on a 64-bit system unless either a) the package is already installed as an ix86 package (e. g. wine, acroread, or the like) or b) the user explicitly requests the package fully qualified.  If I try to do an upgrade, I get some really strange things, such as evolution-data-server-2.28.2-1.3@i586 trying to replace evolution-data-server-32bit-2.28.2-1.3@x86_64, fam-2.7.0-129.11@i586 trying to replace fam-2.7.0-130.1@x86_64, and gnome-vfs2-2.24.0-3.6@i586 trying to replace gnome-vfs2-2.24.2-1.3@x86_64.  Among a bunch of others.
