Your technical description seems right. However, in Sage's convention it
is considered a bug if the pickle jar breaks.

This is not what is supposed to happen. The point of the pickle jar is to
ensure old objects can be unpickled.

Is "needs info" the right status?
'''needs info''' or '''needs work''' are both fine as far as I understand
it.
You can start debugging it by calling
{{{
sage.structure.sage_object.unpickle_all("YOUR_SAGE_ROOT/data/extcode/pickle_jar/pickle_jar.tar.bz2")
}}}
I'll also try to take a look soon-ish.
