Bug Description
When I try to retrieve google calendars, I get this error, but only on one machine (the one I want). The other machine with the same settings, as far as I know, works fine.

 Unable to get the list of Google calendars. The following error occurred:

Request had insufficient authentication scopes. [403=Forbidden]

Furthermore, the "test" that tries logging in with Internet explorer works fine.

On both machines, I have tried disconnecting my account, and then reconnecting. Machine 1 continues to work perfectly. Machine 2 -- the one I want -- has that error relentlessly. I can't find any setting that is different.
