The integration tests for rclone ( http://rclone.org ) have started failing for Dropbox. I haven't changed my code so I suspect something has changed at Dropbox.
This shows up as a failed metadata request which returns a 400 error with no explanation in the body.
I'm deliberately testing a "difficult" file name here `hello? sausage/êé/Hello, 世界/ " ' @ < > & ?/z.txt`.
I suspect my "difficult" file name might be confusing something.
