What steps will reproduce the problem? 1. Install QS ver β56a7 (3825) on Snow Leopard 2. Add pluggins (sorry don't remember which one caused the crash) 3. Now i can't run QS at all because it crashes on load up

How do I fully remove it (remove preferences etc) so that I can reinstall and try again?

From the crash report it looks like the "File Tagging Module" is causing the crash. Just delete it from -

"~/Library/Application Support/Quicksilver/Plugins/File Tagging Module.qsplugin"
