In a unit test case that I am running, I get a KeyError exception on the 4th json object in the json text below. I went through the sub-objects and found that it was the "cpuid" object that is the offending object, but I am completely at a loss as to what is wrong with the formatting.

    response = self.app.post(
        '/machinestats',
        params=dict(record=self.json_encode([
                    {"type": "crash", "instance_id": "xxx",
                     "version": "0.2.0", "build_id": "unknown",
                     "crash_text": "Gah!"},
                    {"type": "machine_info", "machine_info": "I'm awesome.",
                     "version": "0.2.0", "build_id": "unknown",
                     "instance_id": "yyy"},
                    {"machine_info": "Soup", "crash_text": "boom!",
                     "version": "0.2.0", "build_id": "unknown",
                     "instance_id": "zzz", "type": "crash"},
                    {"build_id" : "unknown", "cpu_brand" : "intel",
                     "cpu_count" : 4,
                     "cpuid": {
                               "00000000":
                                    {"eax" :123,"ebx" :456,
                                     "ecx" :789,"edx" :321},
                               "00000001":
                                    {"eax" :123,"ebx" :456,
                                     "ecx" :789,"edx" :321}},
                     "driver_installed" : True,
                     "instance_id" : "yyy",
                     "version" : "0.2.0",
                     "machine_info" : "I'm awesome.",
                     "os_version" : "linux",
                     "physical_memory_mib" : 1024,
                     "product_loaded" : True,
                     "type" : "machine_info",
                     "virtualization_advertised" : True}
                    ])))
