Comment 20 for bug 198111

Well, Ubuntu doesn't develop Evolution, probably it's better to ask on the gnome bugzilla.

The best option I've found so far is to get the private ical feed from each google calendar you want to access locally and add it as a calendar "On the Web". That way, the events show up in evolution and in the clock/calendar widget.

This calendar will be read only as far as Evolution is concerned, but you can sign in to the google calendar web site to make changes and they'll be reflected locally.
