This problem seems NOT related to unicode. In fact, when saying
'encoding="latin1"', my "binary" strings should be converted to unicode
without any kind of issue (my plan was, then, to scan the datastructure
and convert them to native bytes).

The fact is that I get a strange error: "ValueError: operation forbidden
on released memoryview object". Seems like a bug to me. Google shows no
hits. I want to discard any obvious overlooked point.

PS: Just checked... Python 3.1.3 imports the pickle just fine. So busy
migrating my projects to 3.2 (it was my compromise two years ago :), I
don't have time to debug this :).
