My first guess is that your handler doesn't _return_ a 3-tuple. The rest of
your story seems to confirm that, as you seem to get the above error in all
cases where the first element of your args tuple is a length 1 string,
which is the only proper arg for the ord() function, and the code looks ok.
So I think your conclusion is wrong...
