Eh, probably not. I've entered it into my todo list and will probably get
around to it soon.

The immediate cause of this is that you forgot the
include_merged_revisions argument. 8=] But were you to include it, your
code would still be wrong, because...

A callable Python object (which can be a function, or a class instance)
that you pass becomes both the C function and the C baton. Thus, your call
should look like:

       session, # session
       None, # paths
       1, # start
       4, # end
       0, # limit
       False, # discover_changed_paths
       False, # strict_node_history
       False, # include_merged_revisions
       [], # revprops
       receiver # receiver & receiver_baton
               # pool (is omitted)

And the receiver should look like:

def receiver(entry, pool):
         print entry

Look at the bindings' testsuite at
