New version in vivid-proposed (2.9.0+really2.6.2-2ubuntu5) fixed the issue for me too on Ubuntu 15.04.
I have been using it for 4 hours now, I have around 25000 songs, 15 smart playlists, 10 playlists. Everything i tried work well, especially the SQLite performance regression is fixed (Using SQLite 3.8.7.4). I didn't notice any slow startup. I recently cleaned my database, making sure that there were no duplicates in playlists and no circular reference between smart playlists.
