I just applied your patch to clean sources dated 2004.08.04.13.00.00 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 S=F6ren and Ville-Pertti for your efforts!
