Only permit threadsafe pixbuf loaders
Only permit threadsafe pixbuf loaders

When loading an embedded image using gdk-pixbuf, only use threadsafe
pixbuf loaders. This prevents a deadlock with e.g. embedded TIFF images.
This will cause the SVG to render without the embedded image; it will
NOT cause the loading of the SVG to fail.
