Ignore it, it is just IBO looking to see if a table exists by assuming it is
and responding to the exception if it doesn't. You could also choose to make
use of it as well. There is a method to create the table. This allows you to
increment a value on the database and automatically make it so that all
clients schema cache files will regenerate.
