Something like this (untested):

var vectors = new OpenLayers.Layer.Vector("GeoRSS", {
    strategies: [new OpenLayers.Strategy.Fixed()],
    protocol: new OpenLayers.Protocol.HTTP({
        url: "http://yoursite.com/path/to/your/GeoRSS",
        format: new OpenLayers.Format.GeoRSS()
    }),
    eventListeners: {
        loadend: function() {
            if (vectors.features.length === 0) {
                alert("No features were loaded. Is your GeoRSS file valid?");
            }
        }
    }
});
