Why are you trying to use join?  It's not a string function; it's a  
function on lists which accidentally does something useful on normal  
Strings because they're implemented as lists.  ByteStrings aren't  
lists, so there is no useful join, and ghc finds an instantiation of  
join somewhere else and does something unexpected as a result.
