Another thing I find on occasion is an error indicating the 'language'
field in the node table doesn't have a default.  Going to the DB and
supplying a default resolves the issue but is that the correct thing
to do?  I do not have the locale module enabled so there is only the
default or undefined language.  I am at a loss at trying to find an
issue that might exist already for this at issues/drupal.  Does anyone
know of one that might be a good fit for this?
