Comment 7 for bug 1451314

 I found the missing field in settings by comparing the fixed DB in comment #3 above to my broken one..
I was able to use "DB Browser for SQLite" to copy the "settings" fields.

Got past the "Failed to Update Database" but am having other issues now.. of he form
(brewtarget:3972): GLib-GObject-WARNING **: cannot register existing type 'GstObject'

and get stuck at the "Loading..." splash with the BT logo.

I think maybe I'll roll back to 2.1 using the release PPA and see what happens
