App freezes on rotation change with unapplied setting

[Evan Passero]

If you change the theme and then rotate the device the app will freeze. When the rotation state changes the theme updates however.

Steps to recreate

1. Launch App
2. Go to Settings
3. Change theme
4. Rotate screen

Version is 0.8b.
