Sometimes, for version 40, I get the error: (Array.!): undefined array element

This happens when trying to encode the following text that has 4225 characters, in Alphanumeric mode,
with error level L:

The Example.hs code to reproduce the error is:

import Codec.Binary.QRCode

main :: IO ()
main = putStrLn
     . show
     . encode (fromJust $ version 40) L Alphanumeric
     $ "...."

Replace the "...." with the string above and the execution will fail with: (Array.!): undefined array element

If, instead, I am using this code, everything works fine:

import Codec.Binary.QRCode

main :: IO ()
main = putStrLn
     . show
     . encode (fromJust $ version 40) L Alphanumeric
     $ replicate 4225 'A'

5dabe45 fixes the undefined array element issue however the resultant QR code still seems to be invalid.
