[mod_python] .save() for sessions not working ...

>Mmm reducing the script isn't helpful, because something you are doing 
>could inadvertently affect it.
it is reduced to a version that still produces the same error ...

>But it might be that you're saving an 
>empty session?   Dunno.  Which save does it break on?
it breaks at any of the (now commented) sess.safe(), if i uncomment one
of the two sess.save()'s it breaks up ....
