[Setup] Upgrade from 3.3.5 to 4.0.3 fails on "NotFound: <username>"

Sat Feb 12 21:01:19 UTC 2011

I would appreciate any advice solving this migration problem I get when
trying to go from Plone 3.3.5 to 4.0.3.  The instance I'm migrating has
a handful of Plone sites in it.  All but two migrate without problems.
The two that fail have the same problem, quite similar to the one
described in

http://plone.293351.n2.nabble.com/Upgrade-from-3-2-2-to-4-0-2-fails-td5993451.html#a5997783

except nothing I've tried fixes it.  I've tried a "clear and rebuild" of
the catalog and packing in 3.3.5 before migration.

As background, the site has been with Plone a long time, back to the 2.x
series.

Thanks in advance.  Here is the full error message.
