Just for the record…
My problem is apparently related to the fact that I use Dropbox to sync my keychain between two Macs using this technique:
I met with an Apple Genius at the Northbrook IL Store on the morning of August 15.
He said that sharing/syncing keychains was a feature of MobileMe. Unfortunately, now that MobileMe has been discontinued, there is no way to do this that is supported by Apple.
As a result, he declined to attempt to fix my problem.
