Well, I'm not much for deciphering Console errors. But I use Bezel, never primer, and it works for me. I'm on 10.6.2 on a 2008 MBP. Since you have Snow Leopard, I know you have an intel chip, but is it possible you have the first generation of Intel Macs that are 32-bit only? It's possible that using a script I compiled (which I think gets compiled as 64-bit) would crash you.
So two things: 1. I did make a few changes to the script. Maybe they'll help. The original download link now links to those, or you can just use this: http://tr.im/D4BS 2. Open the script in Applescript Edior, save it, and quit it. 3. Move it to ~/Library/Application Support/Quicksilver/Actions 4. Restart QS. Does it work?
