Cannot create new document or presentation

[Heimen Stoffels]

I'm using Ubuntu 13.04 and 12.04 and on both computers it doesn't create a new document or presentation. I'm clicking the buttons but nothing ever happens. It does open already created documents or prsentations fine.

The terminal shows:
[_LOG_LEVEL_WARN 13:04:50.776425] GWoffice.vala:594: Authentication required: <errors xmlns='http://schemas.google.com/g/2005'><error><domain>GData</domain><code>ServiceForbiddenException</code><internalReason>Files must be uploaded using the resumable upload mechanism.</internalReason></error></errors>

How to fix this?
