On 18-Sep-2006, a sane-backends update was released for FC5, also as multi-lib i386 for x86_64. It introduces new sub-packages. The sane-backends-libs-1.0.18-2.fc5.i386.rpm sub-package is missing in the x86_64 updates repo, breaking other i386 multi-lib packages, e.g. wine-core in Extras.
The multilib list needs updated.
