ValueError: insecure string pickle ?

[robert]

cPickle.loads raised "ValueError: insecure string pickle".
The error is from a log file and I cannot reproduce it (quickly).
What can be the cause for that error?

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>

Make sure that your pickle files are being read and written in binary
mode ("rb" and "wb" as the second argument to open()).
