unable to upload GTFS feeds under Chrome

[abyrd]

I’m unable to upload GTFS feeds in analyst-server under Chrome (works in Firefox).

Console error messages:

Uncaught SecurityError: Blocked a frame with origin "https://analyst.conveyal.com" from accessing a frame with origin "null".  The frame requesting access has a protocol of "https", the frame being accessed has a protocol of "data". Protocols must match.

Using Chrome 48.0.2564.97 (Official Build) (64-bit)

Matt's analysis: What’s happening is that the file upload happens in a captive iframe with a data: url. This used to work fine because chrome treated the data url as being the same origin as the containing page. But evidently now it’s decided it’s not, not sure why, because the data page is still served over the same connection.
