[Evolution] Evo locks up switching to calendar page

[Matthew Saltzman <mjs clemson edu>]

I have evolution-3.10.3-1.fc20.x86_64 on Fedora 20.

Somehow, I've managed to get into a situation where, whenever I switch
to the calendar page, Evo freezes solid and has to be forced to
shutdown.  On the page, there are three status-bar notifications that it
is updating a particular Gmail calendar (the same one in all three
notifications)--they show the little activity wheels, but those aren't
moving.

I suppose something needs to be cleared out of my local files or the
cache, but can anyone tell me what that is?

Thanks.
