I can also confirm this bug, but unfortunately neither of the workarounds work for me. I have edited both the calendars and selected_calendars in gconf-editor and done the unchecking/checking in Evolution preferences. After setting apps->evolution->calendar->notify->calendars in gconf-editor, it DID work briefly, but only until reboot. Now I cannot make it work at all.
