I'm running QS b56a7 on Snow Leopard and after many hours of struggle, I finally have almost everything running smoothly (except of course for the plugins known to crash QS). One thing that still doesn't work for me is my old triggers constructed based on the proxy object "current selection". The "command window with selection" works perfectly when invoked using the keystroke defined in the Quicksilver part of the Triggers pref pane. But the "current selection" proxy object seems to be broken.
got the same problem with you. also QS b56a7 on Snow Leopard, nothing happens when I invoke the triggers. Sometimes I cannot even see the "open with" action after select
