    Add default return values to switch statements
    
    We are using g_assert_not_reached() without doing anything, assuming it
    aborts the program. In release builds however, it is ignored.

    Add a return value
    
    When building with G_DISABLE_ASSERT, the g_assert_not_reached()
    statement won't do anything, and we're going to fall through, and the
    compiler will emit a warning that we're not returning anything from a
    function with a return value.

    Fix build
    
    Don't do two things at once and forget to run ninja before pushing.
