As reported on #667070, I have the same problem. But I doesn't get an error.
I onl get the error the first time. Then, the calendar gets set to Read-Only, and Dismissing is completely impossible (there is a bug report for that). To see the error again, I have to disable the Read-Only checkbox first.
Bug 667070 seems to be something different. It claims that alarms are deleted unexpectedly. My problem is that I can *not* dismiss the alarm. Also, I use ICAL instead of WebDAV (Google no longer supports WebDAV). When I used WebDAV, the problem did not occur.
