I had a brief look, and it seems that the first problem is the Mean Square Error
is negative.  If that is wrong, then almost everything else will be.
This comes from Jason's sweep operator.  Unfortunately Jason is no longer 
in PSPP.

Let's start with a simpler example.  Can you tell me what SPSS does with this
syntax (using your original personality.sav):

GET FILE="personality.sav".

recode caution_score (lo thru 35=1) (36 thru hi=2) (missing=2) (else=copy) into 
recode extra_score (lo thru 31=1) (32 thru hi=2) (missing=2) (else=copy) into 
frequencies x1 x2.

GLM agree_score BY x1 x2.
