We're aware of the issues -- Google killed the Contacts API, which has had a knock-on effect to the rest of our Google groupware implementation. There's a patch incoming to fix the issues on the calendar side, though contacts remain to be fixed. I am working on that now

*** Bug 450706 has been marked as a duplicate of this bug. ***

*** Bug 450687 has been marked as a duplicate of this bug. ***

An update: a patch has been added to the Google groupware that disables contacts, allowing other functionality such as calendars to continue working. Still working on a proper fix for contacts, but this should resolve this issue at the very least.

Patch is now live on Tumbleweed and Arch, should be coming to other distributions soon
