filesDownload throws when there is no file to download

When calling filesDownload for an inexistent file it throws the following exception:

VM23710:1 Uncaught DOMException: Failed to read the 'responseText' property from 'XMLHttpRequest': The value is only accessible if the object's 'responseType' is '' or 'text' (was 'blob')
    at Error (native)

From the stack trace, it look like the problem lies with the superagent lib used by dropbox.

Chrome 54, dropbox-2.4.0

No, unfortunately I don’t have an ETA on this right now. We’ll follow up here once we have an update for you.
