Title: mkrueger,slluis

It seems that in custom implementations of ITooltipProvider(extention registered via "/MonoDevelop/SourceEditor2/TooltipProviders"), GetItem never gets called because the inner routine only takes the first non-null tooltip item object found. And CompilationErrorTooltipProvider is always provides a non-null TooltipItem object (although e.g. there is no compilation error) in its GetItem method.
