Apparently, you have object with a "size" attribute (lacking "get_size")
and (other) objects with a "get_size" attribute (but without "size).

You can use:	    "file_size item/size | item/get_size | nothing"
to account for these cases (and the one that you hit an object
without both "size" and "get_size").
