There seems to be a consistency issue with shindig's treatment of relative URIs in gadget specs. Some more details are at:
http://groups.google.com/group/opensocial-api/browse_thread/thread/756ecef6c4d70a2c# The method ModulePrefs#getUriAttribute should probably be some static utility method that can be called from multiple places, in this case, OAuthService, which via XmlUtil is not allowing URIs that don't start with http or https. Relative URIs need to be resolved first before this validation is done. -Randy Hudson
