Hi Rob,

This isn't the first time I've seen this '.' issue, but in most case it
was fine. 
The thing interesting is after I saw your email, I tried to access my
account with songqiang1304521@xxxxxxxxx(just without '.'), and it
succeeded! So maybe google just removed the '.' in my account everytime
I logged in. I think I'll send next version of my patch with my email
account without '.'.

yours,
Song Qiang
