Upgrading to Leopard leaves two versions of Stickies

When I upgraded Mac OS X to Leopard, I ended up with two versions of Stickies.app in the file system. One was in the main Applications/ folder, and one was in Applications/Utilities/. I run most of my apps using Quicksilver, and the effect was that Quicksilver would default to the older Stickies.app, which doesn't run on Leopard (silent failure, too -- so you don't know whether it's Quicksilver or something else). Deleting the old version from the Applications/Utilities/ folder solved the problem.
