Other folks in the office have seen this, and it seems to happen when you manually lock the screen and leave the lock-screen up long enough for the lock-screen timeout. That is, once you log in the system notices that the lock-screen timeout has passed and doesn't account for the fact that the screen was actually locked the whole time.

I believe this only happens when I manually lock it with my ThinkVantage key that I have bound to the lock-screen shortcut, but I can't be sure of that. I've seen this for a while now, but assumed it was some bug caused by either a borked compiz or some kind of delay catch-up happening because gnome-screensaver took too long to swap in. But I just upgraded to the latest trusty compiz that has tons of bugfixes, and the new lock screen keeps gnome-screensaver swapped in nicely.
