Insecure string pickle?

[Gaetan Corneau]

Hello,

I have put objects (magazine routing lists) in a shelf. I can list all the
keys, and I can load all objects except one. 
When I try to load a particular list (using it's name), I get the following
error message:
ValueError: insecure string pickle

What does that mean?

TIA,
