there’s this behavior where when one of our team members is trying to initially login (register) via facebook, the email field stays blank … and disabled. Thus she can not login via Facebook because the ‘Create Account’ button is disabled as well.
This is on OS X in Safari with locale ‘en’:
… it’s the same on OS X in Chrome with locale ‘de’:
(she has now logged in via Google account, to get stuff going)
At this very same workstation, for a different facebook user account the email text box get’s preset without a problem.
 it’s with version 0.9.8.10
