I have recently tried using `auto-package-update` tool to keep all of my Emacs packages up-to-date. It appears to work well. However, the update seems to have broken my Zenburn theme. I believe I had gotten this error and breakage before when I tried updating Zenburn manually. At the time I resorted to just keeping the older version and not dealing with the issue. Below is the messaging I received.

Any tips on how to fix this are appreciated.
