OAuth admin interface and x_sendfile_header

[thomasbalsloev]

Hi Assaf!

I've had some trouble with getting the oauth admin interface to work in "production" env. I just got an empty page and nothing helpful in the logs.
After some fiddling I found out that this config line was the culprit:

-- # Specifies the header that your server uses for sending files
config.action_dispatch.x_sendfile_header = "X-Sendfile"

I haven't got a clue as to why this breaks the interface, or if others have encountered the same problems.
But I thought I would mention it and maybe you could enlighten my as to what is the reason for the breakage.

BTW, thanks for a great gem!

Regards,
Thomas.
