I can't help with this one.  As Gracjan noted, it is probably because  
your binary data is not valid as UTF-8 text.

But this one, although likely another symptom of the same binary  
problem, I have fixed in the darcs repo for HaXml.  (Basically, the  
'white' function was only permitting ASCII whitespace - I have now  
extended it to allow for Unicode whitespace characters also.)
