I took a look at your files, and it looks like that subject has a
different number of covariates of interest than the rest (see the G
matrix).  So you either need to fix the G matrix or adjust the
contrast vector.  Our scripts should really give you better feedback
when this happens, I'll bump that up on my priority list.
