svn-1696 is kinda hard on the slug.
Unfortunately sqlite2 support is broken, so you have to upgrade to sqlite3.
If you have smart playlists and whatnot you probably want to keep your database, so you gotta do a
sqlite /path/to/songs.db .dump | sqlite3 /path/to/songs3.db plus change the config to use sqlite3.
If you don’t give a flying freck on your database, then you can just tell firefly to use sqlite3, and it will rebuild a database from scratch.
