Comment:

 Works for me if I fill in a suitable class for wtsource:

 {{{
 #!python

     class WeightSource:
         def __init__(self):
             pass

         def get_maxweight(self):
             return 1234.;

         def get_weight(self, doc):
             return doc.get_docid()
 }}}

 I wonder if eugene_beast fail to supply a suitable class there.  Anyway,
 the example does work.

 I'm going to try to slot this in now.
