I just applied your patch to clean sources dated 2004. and ran
some tests. Everything seems to be working as it should (just like after the
serialization patch from Ville-Pertti that I tried earlier). I will continue
running with this patch applied to see if it stays stable.

Thank you Sören and Ville-Pertti for your efforts!
