No!  What I say is that the display code should call
image-type-available-p before trying to lookup image type or determine
whether the image type is valid.

That certainly does not happen if you open an image file and are using
auto-image-file-mode, for example.  From this discussion, I gather that
it does happen if you use create-image, save the result and then load it
and try to display it...
