    About once a day with no obvious provocation I've had mail crash, then messages right afterwards. The message I get on the mail crash is:

    Application Specific Information:
    *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'missing variable binding for (null)'
    abort() called
    terminating with uncaught exception of type NSException

    On console, I keep seeing "skipping upgrade for locked keychain."

    Any ideas?

    ...and something else weird just happened. On messages, all the names were replaced by phone numbers. When I tried to start a new message and typed in a name, it crashed. When I reopened it, it was back to normal. ????????
