Corrupt 12.04 automatic update

Installing 12.04 from scratch on a few AMD systems is causing these same
errors for me, and I see others complaining about them.

However, the systems are still useable so Ive ignored them. Ubuntu has
recently updated several desktop components, so I haven't yet noticed if the
errors are gone.

But they will be.
