Nice find!

We've updated the default value for guidAttr to be entryUUID instead of None.

I've narrowed it down to requested items not being found in memcached, but the fact that I am a crappy python programmer combined with the fact that getting calendarserver is NOT part of my day job, I have been unable to dig in any further and come up with a cause.

Can we run calendarserver--any version--against a standard memcached distribution?
