Steps to reproduce the problem:
1. Unable to reproduce issue on demand.
2. On a machine that is failing, logging out of chrome os and back in seems to resolve the issue.

What is the expected behavior?
Should return the email address of the logged in user.

What went wrong?
While everything works correctly most of the time, we are seeing very sporadic issues where a null is returned instead.  We have tried to reproduce the issue on demand, but have not been able to do so.  Once the issue occurs, the only fix has been to have the user logout and back in.

Did this work before? N/A
