Comment 10 for bug 1049028

It is possible to integrate Google Calendar and Contacts anyway:

For the calendar, add an "on the web" calendar and enter the ical-adress of your Google calendar. If you have dates with e-mail-notification, you get an endless series of warning popups saying evolution calendar doesn't support e-mail notifications for dates, so you have to kill it and the process "evolution-calendar-factory".

Google contacts can be integrated the normal way, so I suppose it's really about Google calendar here.
