Attempting to update to a recent Raw Hide snapshot, I see this: Dependencies Resolved ============================================================================= Package Arch Version Repository Size ============================================================================= Installing: nautilus-sendto i386 0.10-1.fc7 development 79 k replacing nautilus-sendto-bluetooth.x86_64 0.8-4.fc7 nautilus-sendto x86_64 0.10-1.fc7 development 82 k replacing nautilus-sendto-bluetooth.x86_64 0.8-4.fc7 I don't have the i386 nautilus-sendto-bluetooth installed, so installing the i386 nautilus-sendto seems kinda wrong.
This has come up before and I think the actual behavior has flip-flopped over time... given that the obsolete doesn't specify an arch (it can't really), what the "right" thing to do is hard to say. By installing both arches, it's consistent with if you just did the install... but not with an update. I guess it probably makes more sense to follow the update path.
