Till, this is probably fixed by now. The bug was probably due to the
fact that theSetExprs data member of var_expr was not being serialized
at all. However, I cannot check if it is indeed fixed, because you did
not tell me how to reproduce the bug. So, I am assigning this bug to
you, so that you check it.
