Hi.
I have an instant crash here while trying to start mixxx 1.12-alpha (git master r4501)

archlinux_64 T64

[Ihr Datenbankschema konnte nicht auf Version 23 aktualisiert werden
Ihre Datei mixxxdb.sqlite ist möglicherweise beschädigt.
Versuchen Sie die Datei umzubenennen und Mixxx erneut zu starten.
