Examining my flattened relationships, nothing looked funny, but I 
zapped 'em anyway just for grins. The app started. (Great!) Then I 
started restoring the relationships one by one. Each time, the app 
started. (Great!) And finally I had restored all the relationships, 
and the app started. (Great! Wait, what the...?)

My model is now fully restored from CVS, and everything works 
correctly, just like it always did.

I must have fallen down a rabbit hole. Or more likely, Eclipse 
wasn't correctly updating its build directory.

Thanks for the help,

zak.
