OK, this is because ia32-libs-gtk is missing a few things.

IM modules and pixbuf loaders are handled specifically by looking
at /usr/lib32, because the paths to the modules are hardcoded in
configuration files. This is why, for them, the /usr/lib32 symlink is
enough.

However, for the others, multiarch paths are searched first. Therefore,
if you want correct support for theme engines, print backends, GTK+
modules and filesystem backends, you only need to add the following
symbolic links:
/usr/lib/gtk-2.0/i486-pc-linux-gnu => /emul/ia32/usr/lib/gtk-2.0
/usr/lib/gtk-2.0/@APIVER@/i486-pc-linux-gnu => /emul/ia32/usr/lib/gtk-2.0/@APIVER@

(@APIVER@ currently being 2.10.0)

Feel free to ask us for more information if this is not enough.

Cheers,
