A corrupted pickle. The error is raised if a string in the dump does not
both start and end with " or '. One way to provoke the error:

>>> from cPickle import loads, dumps
>>> s = dumps("abc")
>>> s
"S'abc'\np1\n." # that's what it should look like
>>> loads("S'abc") # but make it too short
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
