In general in this file, it is the status field, not the state field, that
contains values like OPEN and CLOSED.  Indeed, in the first error case, it
is the field status that is initialized.  I have thus assumed that all of
the error handling code should be the same, and moved it to the end of the
function to emphasize its commonality.
