 - fb6a1ff (gnu: appstream-glib: Propagate gdk-pixbuf+svg rather than gdk-pixbuf)
 - 4fb525d (gnu: weasyprint: Propagate gdk-pixbuf+svg rather than gdk-pixbuf)

These commits were made to resolve a gdk-pixbuf loaders clash that could occur
in a profile when both gdk-pixbuf and gdk-pixbuf+svg were propagated.
Unfortunately, librsvg really needs to propagate gdk-pixbuf itself, which
would introduce a cycle.  Packages such as 'efl' were broken as a result of
not propagating gdk-pixbuf.

A more definitive fix will be proposed for core-updates, which includes a
profile hook to generate the gdk-pixbuf loaders.cache file, as well as a build
phase and search path specification, that should resolve the issue for good.
