I've created a new google akonadi resource, using KDE 4.8.3 and akonadi-google 0.3.1. I can successfully authenticate and get the list of calendars and task lists, but then when I click ok, instead of fetching the calendar from google and displaying it, akonadi gives me the following error:

akonadi_googlecalendar_resource_9(11079) KGoogle::AccessManagerPrivate::nam_replyReceived: User quota exceeded. 
akonadi_googlecalendar_resource_9(11079) KGoogle::AccessManagerPrivate::nam_replyReceived: "{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "backendError",
    "message": "Backend Error"
   }
  ],
  "code": 503,
  "message": "Backend Error"
 }
}
" 

And nothing is fetched from google.

Thanks.
