Crash occurs in General (Application Language, Theme, Default Status, Default Payee) Settings

Expected behavior

When I click on the General settings, then click any of its sub settings a dialog comes up.I expected the app to rotate to landscape and back to portrait with the dialog successfully without crashing.
