    Bug 753059 - Crash in spell check dialog when clicking replace buttons with no suggestion selected
    
    Avoid the crash by sticking to the GtkHTML based composer behavior. When there
    are suggestions presented, automatically select the first one. If no suggestion
    is presented, make the 'Replace' and 'Replace All' buttons insensitive.
