Correct. The very first thing I tried (which usually worked before with
db4o errors), was to delete my node.db4o.crypt file. That had no effect
this time. Instead, deleting datastore/*, or starting with a fresh
installation, with the wizard, got the node running. Drastic, I know.
(Although, Tommy in the bug report mentioned he was able to reproduce
the error even with a clean wizard installation :S.)

So far my node is running. The only way I can think of reproducing it
is by going back to the 1407 that I was using for months -- probably
recreate my datastore with it -- and then upgrade to 1409 again :S.
