[CalendarServer-users] Can't accept invitations?

[David Scheidt]

I've got a calendar server set up on a FreeBSD 7.1-PRERELEASE machine,
using the supplied sample XML setup (with the addition of actual
working email addresses).  I'm using iCal on a Mac as the client.
When I attempt to accept an invitation, I get an "internal server
error" in ical.  Here's what the error.log file has to say:
