"result" is actually a class of type suds.sax.text.Text which is a subclass of unicode. 
Seems that either the StringIO or expat parser has a problem unicode.  Probably the 
StringIO.  The reason it works to write to a file and then read it again is that when you 
read(), you now have a str object.  When reading directly from a file, the parser is 
reading a file-like object.

So, this:

 > print 'From string:', p.parse(string=str(result))

works and this:

 > print 'From string:', p.parse(string=unicode(result))

does not.

I'll look into this further.
