Got the same problem with the clock/calendar.
Found that rename/remove the ~/.gnome2 folder was my solution to the problem.
Before I did that, I tried to reinstall evolution, remove everything under ~/.gconf/apps/evolution, disable weather reports, but the only thing that worked for me was renaming the ~/gnome2 folder.
