I suspect it is not appropriate to refer to buffer-local variables of
the current buffer inside image loading functions:

diff --git a/src/image.c b/src/image.c
index 1a2c0e2..0bebd45 100644

          image_error ("Invalid image data `%s'", data, Qnil);
          return 0;
        }
-      success_p = svg_load_image (f, img, SDATA (data), SBYTES (data));
+      original_filename = BVAR (current_buffer, filename);
+      success_p = svg_load_image (f, img, SDATA (data), SBYTES (data),
+                                  SDATA(original_filename));
     }
 
   return success_p;

Maybe SVG image descriptors should accept the property `:base-uri' or
something?
