This problem went away in 0.10, but has re-appeared in a slightly different
context in the current trunk.
In this script, I have something like
split a into b,c
d = join b, x;
pd = project d;
e = union pd, c;
split e into f,g
h = project f (this is where I get the incorrect fieldname being used
causing an error. )
