When I upload an image from /admin/products/new, it saves a blank file

Repo steps:

1. Go to /admin/products/new click upload (unstylized button)
2. Select file
3. Fill out product details
4. Press save

Expected:

The image uploads and is saved

Actual result:

When I go back to edit the product, a blank place holder is found. A stylized button is there now and the upload widget (rather than just the browse dialog) appears.

Notes:

Testing on latest version of Chrome on OSx
