This bug occurs during the initial multi-upload process, before the "Import" button is pressed when the small derivative is created for the multi-upload screen.

I have attached two screenshots - the two images are the same with the exception of the case of the extension - jpg vs JPG (see first screenshot). The second screen shot shows that the lower case reference copy is NOT uploaded to the /uploads/tmp directory - only the derivative for that image. I think this is the source of the issue - this thumbnail then becomes the reference copy once the "Import" button is pressed.
