Bugs bug me a lot :). I spend a couple of hours trying to reduce my
pickle to something I could post (the original pickle has tons of
propietary information):

http://bugs.python.org/issue11286

I got a reproductible pickle testcase in only 41 bytes.

Seems to be a SERIOUS regression in 3.2.

I can't progress further. Pickle internals are out of my expertise.
