Per Robert's comment 55, there is still an open issue with gdk-pixbuf hard-coding /usr/lib that makes it stop working in the ia32-libs context. The same is true of the gio modules, which have been broken since at least Jaunty. I've opened tasks against each of them.
I will also note that libjasper1 is also not in ia32-libs, and gdk-pixbuf depends on it, so it should be added.
