Don't worry about it, I can reproduce it here on 10.6.2.  I'm not sure whether 
it was something in Emacs that changed, or something in one of the point 
releases, as I'm pretty sure I debugged and fixed this same issue this past 
summer (cause was a missing function prototype) working under 10.6.1.

I'm not sure at the moment when I will have time to dig into this though.
