Tested on Safari, Chrome and Webkit Mac app.

The file on this link: https://reminis-pip-pab.s3.amazonaws.com/DW_ET.jpg

It gives "Invalid JPEG metadata: Invalid segment size." error on Webkit Mac App. It is in function parseMetaData(file, callback, options, data) line 137

It gives a strange file attached below on load. It's 4 bytes jpeg. and canvas.toBlob gives null blob.

There is no problem with Chrome and Safari with the same code.
