To be honest, the simplest suggestion is to not use 1.5 for
non-testing work until it is completed and released! We do appreciate
beta-testing, and I will make sure to look at the details of your
issue later this week, but 1.5 is unreleased code, and we have already
changed the Sqlite schema several times, and plan to either change it
again significantly or possibly even remove the Sqlite database before
release.
