When --depclean is called with package arguments, only the given packages are considered for removal. This means it worked as expected. Running --depclean without argument or giving all packages in the cycle as arguments at once should work. Maybe this is a dupe of bug 336889?

With the introduction of virtual/pkgconfig into the tree, dev-libs/glib is no longer pulled into @system if dev-libs/pkgconf[pkg-config] is on the system. However, dev-libs/glib and x11-misc/shared-mime-info depend on one another, so portage is unable to detect that they are no longer needed. It seems to me that we could resolve this with reachability analysis. We could start with the set of all packages merged on the system, which I will call set A, and a set of all packages explicitly enumerated in @system and @world, which I will call set B. Then removing a package from set B, we can do either a depth first search or a breadth first search on its dependency graph, removing all packages in sets A and B that we encounter from them respectively. We will then repeat, taking the next item from set B. When set B is empty, all packages remaining in set A can be removed.

One of those two were in @world.
