The couldn't load state errors are probably from a product not getting
initialized properly.  If you set up your STUPID_LOG_FILE environment
variable and point it at a file before starting Zope (if you haven't
already), you may be able to see a failed product init before the state
errors, which would give you a clue.  That said, from your description,
it's probably kmnetnews that's not getting inited properly.  I haven't
seen  Kevin Dangoor around lately, I wonder if he's still maintaining
it.
