Hmm. Then the best is to call explain_pickle directly on those files,
rather than guessing which object causes trouble. What you can try is
to extract the pickle jar in /tmp:
tar jxvf /opt/sage-4.3.1/data/extcode/pickle_jar/pickle_jar.tar.bz2
and run:
sage:
explain_pickle(file="/tmp/pickle_jar/_class__sage_graphs_graph_DiGraph__.sobj")
pg_DiGraph = unpickle_global('sage.graphs.graph', 'DiGraph')
si1 = unpickle_newobj(pg_DiGraph, ())
pg_NetworkXGraphBackend =
unpickle_global('sage.graphs.base.graph_backends', 'NetworkXGraphBackend')
si2 = unpickle_newobj(pg_NetworkXGraphBackend, ())
pg_XDiGraph = unpickle_global('networkx.xdigraph', 'XDiGraph')
si3 = unpickle_newobj(pg_XDiGraph, ())
si4 = {}
unpickle_build(si3, {'name':'', 'pred':{}, 'selfloops':False, 'succ':si4,
'adj':si4, 'multiedges':False})
unpickle_build(si2, {'_nxg':si3})
unpickle_build(si1, {'_weighted':False, '_boundary':[], '_backend':si2,
'_pos':None})
si1
Good luck!
