I don’t think so.  :-)

variants of gdk-pixbuf in the dependency graph, and it turns out that

The solution to this is to “debug” the dependency graph and arrange
things so that the dependency graph of GTK+ includes only one variant of
gdk-pixbuf.  (It might be that it’s easier said than done, but we have
to try!)
