Description of problem: When I installed from rawhide tree on x86_64 box, scim-bridge-gtk.i386 wasn't installed. right now scim's xinput script that is to configure IM at the startup time is checking if both immodules are available. so this makes XIM enabled then because scim-bridge-gtk.x86_64 only is available. The only way of enabling scim-bridge instead of XIM is to get both scim-bridge-gtk packages installed for multilib because there are no way of having different IM settings for an arch on gtk2.
Also confirmed that this is still happening on latest x86_64 rawhide.
This is the expected behavior. You have a requires on scim-bridge-gtk. The x86_64 package satisfies that requires. If you want both installed, you either need a) the package listed in comps (but that has the other downsides that have been gone through at length) or b) have things require the actual libraries
Probably we can fix this with an appropriate requires in scim-lang-*.
I built scim-1.4.7-6.fc8 for this.
Confirmed fixed with latest rawhide for Japanese install.
