Good to know ObjDev support is already involved in helping you. Their hunch of "a bug regarding 32/64bit compatibility"" sounds like the best explanation for your LB/Automator problem now. I was wondering if you're running Lion on a system that can't be updated to Mountain Lion, but had overlooked the possible 32bit factor. Even my oldest system, a 2007 MBP, runs in 64bit.
