During my troubleshooting efforts I resorted to the simple trick of quitting Quicksilver and simply moving its preference file (located with other preference files in ~/Library/Preferences) to my desktop, forcing Quicksilver to re-create a clean new preference file. This fixed the issue, but it also forced me to dive back into my preferences to tweak, toggle and change some of the options I use to make Quicksilver do what I want."
