    Avoid crashing when year view's weather icon is NULL
    
    This is not a proper solution, because I don't see how it could possibly
    ever be NULL here. But a huge number of users are reporting this crash,
    so we have to try something.
    
    This fixes #299, but I'm not happy with it.
