25410	Empty ClearableFileInput raises ValueError	vfigueiro	Tim Graham	"Having an empty file field raises ValueError whenever the ClearableFileInput widget is rendered in the admin or in a custom form. It prevents the rendering of the form in change mode (works in creation mode).

I guess this started happening on Python 2.7 after #24727 was fixed in 5c412dd8a724b263489c1bd7a2fea381460665d7.
