The reported problem looks as if the REQUEST were used
after it has been closed.

This can for example happen when an acquisition wrapper
is cached in a "_v_" variable. The wrapper has at its
bottom a stale REQUEST object, now closed.
A closed REQUEST has lost all content of its "other", among them
"SESSION".
