Use:

   def handler(req):
     req.status = apache.HTTP_BAD_REQUEST
     req.content_type = 'text/html'
     req.write(....)
     return apache.DONE

Setting req.status and req.content_type must be done before first  
write as
you found at.

Setting req.status and returning apache.DONE is key as that is what  
tells
Apache not to format its own error response.
