+# Bug 1714072 describes a situation where a resource provider is present in the
+# body of an allocation, but the resources object is empty. There should be at
+# least one resource class and value pair. If there is not a 400 response
+# should be returned. This gabbit file demonstrates the problem: a 500 on the final
+# test.
