This bug seems to have resolved itself since reporting it. I took a look at the package install logs and there not obviously connected package that would have fixed this.
Here's what's been installed since reporting the bug.

Status in Unity: New Status in “unity” package in Ubuntu: New Bug description: After idling for some time my desktop locks. When I return and enter the password, it unlocks and I briefly see my desktop and open applications before it locks itself again. After entering the password (again), it seems to work fine. Expected behavior: The desktop shouldn't lock immediately after unlocking. Reproduce: 1. Let the screen lock on its own. Using CTRL-ALT-L seems to only require unlocking once. 2. Try to unlock the desktop using your password. It will relock (for me). I have a feeling it might have something to do with the monitor going to sleep, which might explain why CTRL-ALT-L seems to work (the monitor never sleeps.)
