SolrResponse throws exceptions.AttributeError when printed

[Esteve Fernandez]

When printing a SolrResponse object, an AttributeError exception is raised due to an unknown instance variable (self.rawResponse):

 File "/usr/lib/python2.6/dist-packages/twisted/internet/defer.py", line 893, in _inlineCallbacks
    result = g.send(result)
  File "/tmp/foo.py", line 10, in bar
    print res
  File "/home/esteve/fluidinfo/src/dependencies/source-dependencies/txsolr/trunk/txsolr/response.py", line 172, in __repr__
    return 'SolrResponse: %s' % repr(self.rawResponse)
exceptions.AttributeError: 'JSONSolrResponse' object has no attribute 'rawResponse'
