Keychain reports: Access to this object is restricted - because I just had the problem again, and because it really annoys me that this nonsense is still there after so long: never use MobileMe for keychain synchronization. Sometimes it works for a while, but that's deceptive. sooner or later the sync will mess up the keychain and in the worst case you have to reset it completely (or check if you have a functioning keychain in TimeMachine). To Apple: this is really shit.
