graph.PendingAncestryResult(['<email address hidden>'], b.repository).get_keys()

['<email address hidden>', '<email address hidden>', '<email address hidden>', '<email address hidden>', '<email address hidden>', '<email address hidden>']

after copying the repo down with lftp, remove the stacked parameter
source = b.repository._get_source(b.repository._format)
stream = source.get_stream(graph.PendingAncestryResult(['<email address hidden>'], b.repository))
>>> for kind, sub in stream:
... print kind
... for record in sub:
... print record.key
... print len(record.get_bytes_as(record.storage_kind))
