title: Facebook Connect: proxied_email not always returned by users_getInfo
body: <p>Today I realized that FB Connect does not return the proxied_email field in about 4 out of 5 times. (I can reproduce this with a single users repeatedly, so this obviously does not have anything to do with privacy options or permissions)</p>
  
  <p>It definitely worked fine last week ago.</p>
  
  <p>I could not find any official info that this field is going to be removed or anything, so... 
  Does anybody else have this problem? Is there anything I am doing wrong that could be causing this behavior? Or is Facebook just having a bad day?</p>
