Can't boot instance because of instance_type wrong pass

In version:
2011.3-dev (2011.3-workspace:tarmac-20110602174653-azonyll6ctjjtxvf)

Commenting the "request_spec" argument makes it work:
     rpc.cast(context,
                     FLAGS.scheduler_topic,
                     {"method": "run_instance",
                      "args": {"topic": FLAGS.compute_topic,
                               "instance_id": instance_id,
                               #"request_spec": {
                               # 'instance_type': instance_type,
                               # 'filter':
                               # 'nova.scheduler.host_filter.'
                               # 'InstanceTypeFilter',
                               #},
                               "availability_zone": availability_zone,
                               "injected_files": injected_files,
                               "admin_password": admin_password,
                              },
                     })

[root@cloud ~]$ nova boot --flavor 1 --image 1206608969 test
datetime.datetime(2011, 5, 20, 12, 25, 49) is not JSON serializable (HTTP 500)

[root@cloud ~]$ sudo nova-manage version list

Why am I not seeing this problem in my environment? I'm able to create instances without issue.

Which version of json are you running?

This issue does appear only on custom created instance types, because they have real time instead of None in created_at field.
Built-in (EC2-like) instance types are not affected.

I can confirm I'm testing with custom instance types.

Ah ... interesting. Ok, let me look further. Thanks.
