Figured Out the Sync in a Blink Problem

I figured out my problem with Sync in a Blink. It turns out that my five mystery different contacts had no name or company name - only email addresses. I never could find them in the Contacts app but I happened to install the iPhone Peeps app (sort of a Coverflow for contacts thing - not as great as it could be, but that's another story). Anyway, one good thing about Peeps is that it showed these five mystery contacts and I was able to edit them and add names.

Once I did that, Sync in a Blink's show ungrouped contacts option stopped crashing the app and instead correctly displayed these five rogue contacts.
