The meanings of Type errors - specifically 8!

I had the same error .. do you get the gray veil to restart? I do ... anyway, it seems to point to an HFS issue, but for some reason neither apple disk utility nor techtool pro 4 can pick up the HFS corruption .. interestingly, I duplicated the file then deleted the original but forgot to remove it from trash. When I tried SD again, it fell over in the trash folder - so I assumed it must have been the file. But when I deleted it and restarted, it fell over elsewhere ... I use 10.3.9 and never tried it on any previous versions .. maybe 10.3.9 introduced a subtle change .. ?
