Comment 11 for bug 1388515

I tried to file a report on this issue with an updated system, but it was marked invalid for the same reason mentioned here in Shnatsel's comment.

The temporary workaround for the crashing issue, is to delete the CalDav file in /home/.config/evolution/sorces , but you're still unable to add caldav calendars. Only the default google calendar works (ie. the one associated with your personal email).
