The view that I am experiencing this error on is rather nasty, so
much so that I am going to solve the problem it was supposed to
solve in another way.

On another (possibly related) note, the same view seems to pose
problems when I do a 'SELECT count(*) from view_name'.

If I do a 'SELECT * from view_name' and get 8 rows of data, when I
do a 'SELECT count(*) from view_name' I get 8 rows of the
number 1 returned.

In any case I'll try and distill both of these down to a slightly
less horrific testcase and send it in.
