The cambalache package does the right thing by wrapping the program to
setenv GDK_PIXBUF_MODULE_FILE to the value it has while building the
package.  glib-or-gtk build system sets GDK_PIXBUF_MODULE_FILE while
building the package.  Note that gdkpixbuf and perhaps
librsvg-for-system must be in inputs.

Florian
