+If the special remote responds with CLAIMURL-FAILURE, then addurl will not
+use it.
+
+There might be some other way the special remote could fail that breaks
+addurl. The only one I can see currently is if the special remote sends
+something that's not a valid response in the protocol.
+
+So I second Ilya, we need a protocol dump or a better explanation about what
+behavior you are seeing.
