I was working with brim to update/create a few contacts
and I was going to change the name of a calendar item.
I checked my error log and noticed this:
It looks like it might be related to the calendar. I
couldn't tell you where exactly its required, but I
hadn't dont alot with the calendar when I recieved this
error. It might be on the standard view page. I view a
month at a time btw.
