Thanks to both. It's funny since I have some code I am sure worked OK a
year ago but when I ran it this week the only change I had to make was to
insert an explicit conversion from QQ to GF(ell).
Nils may be interested to know that this is for a project on making a
database of modular forms mo

I'm sure this used to work:
sage: F = GF(2)
sage: r = 5/3
sage: F(1)*r
TypeError: unsupported operand parent(s) for *: 'Finite Field of size
2' and 'Rational Field'
Of course I know that the could not be a coercion from QQ to GF(2) but
there is a conversion which works fine (when the denominator
