Comment (by was):
The attached patch fixes the problem by explicitly not saving builtin (or
not)) functions or classes, since in fact defining classes also breaks
load_session and save_session.
It just occurred to me that one can still make sessions that can't be
reloaded. E.g.,
{{{
class Foo:
pass
f = Foo()
}}}
Then save_session followed by quit and load_session fails. However, I
doubt there is any good way to deal with this. Fortunately, in the above
case, unlike in the case that this bug is about, one can simply re-
evaluate the code to define Foo, and suddenly load_session works fine.
I've put a comment abou this in the patch.
