||There are file conflicts with the package libclutter-devel-doc-1.26.4-alt1.noarch, for example, /usr/share/gtk-doc/html/clutter/CallyActor.html (125 file conflicts in total). Moreover, the packages have no explicit conflicts with each other. You should add explicit conflicts, or, if conflicts are avoidable, consider using alternatives.
||The package has a significant amount of architecture-independent data in /usr/share, while it is an architecture-dependent package. This is wasteful of mirror space and bandwidth, as we then end up with multiple copies of this data, one for each architecture. If the data in /usr/share is not architecture-independent, it is a policy violation, and in this case, you should move that data elsewhere.
