The user is presented with a menu item to add a gadget even if Shindig is not available. If a user attempts to upload a gadget they receive a rather uninformative "There was a problem registering this gadget " error. The log indicates a more useful error of "[java] java.lang.Exception: There was a problem connecting to the Shindig metadata service"
At the very least the UI should report the actual error. Ideally the option to upload the gadget would not be displayed in the first place.
