GFC username is '-1' when logging in on Safari or Chrome

I would like to quickly report this problem.

I am using a Google Account to test this

When you try to connect to leave a comment and you are using Safari or Chrome, the username is set to '-1' (then '-2', '-3', etc) and the picture is not loaded.

When you try to do the same on Firefox, it seems to work.

I see that there is a similar issue with 7.x

I have tried to use the 6.x-1.x-dev but I did not notice any difference.
