Hi,

I'm reassigning this to libgtk2.0-0 as the actual source must be
fixed. Nothing ia32-libs-gtk can do there.

That is already wrong. gtk really should use an architecture specific
path or this won't work for ia32-libs and amd64-libs.
E.g. /usr/lib/gtk-2.0/$(DEB_HOST_GNU_TYPE)/2.10.0/loaders/../loader-files.d

Alternatively it could check for
/usr/lib32/gtk-2.0/2.10.0/loaders/../loader-files.d first and fallback
to /usr/lib/gtk-2.0/2.10.0/loaders/../loader-files.d otherwise. But
that is less elegant.

That file should actualy be obsoleted by the loader-files.d
approach. You might have noticed the respective
/etc/gtk-2.0/gdk-pixbuf.loaders file has gone.

Unlucky us. Shouldn't have worked in the first place though.
