It's possible - albeit unlikely - that gdk-pixbuf isn't present in the sysroot
when a recipe inheriting this class is and the sysroot is finalised.
One example would be if the sstate archive has librsvg but not gdk-pixbuf:
librsvg will be extracted from the sstate but gdk-pixbuf will be built to "fill
in the gap". In this situation the setscene completion hook installed by
pixbufcache.bbclass will attempt to execute gdk-pixbuf-query-loaders, but that
binary hasn't been installed by gdk-pixbuf yet.
Also add gdk-pixbuf-native to DEPENDS in native builds to ensure that the
binaries we expect will be present, as it's possible to build loaders without
linking to GdkPixbuf.
