Hi! I'm using ubuntu 13.10 64bit and had just upgraded to rainlendar 2.12.b136-1.
When getting google tasks (gmail), rainlendar crashes after login at my gmail-account, just before I could click on the permit-button.
So I can't get the tasks into my calendar. If I would add google-calendars with google 3 version, the same crash would happen. So I used the old version for it.
Before I upgraded rainlendar, I had trouble with offline view. After starting system often no events were shown, althoug I had checked offline available.
