Open Stack

This problem occurs on a stable Ussuri Devstack. I issue this command to 
create a protected image:

$ openstack image create myimage2 --file ~/myvm1.qcow2 --disk-format 
qcow2  --protected

and get this error message back:

BadRequestException: 400: Client Error for url: 
http://192.168.1.200/image/v2/images, 400 Bad Request: On 
instance['protected']:: 'type': 
'boolean'}: {'description': 'If true, image 
will not be deletable.',: 'True': Provided object does 
not match schema 'image': 'True' is not of type 
'boolean': Failed validating 'type' in 
schema['properties']['protected']:

It seems that image creation fails because

'True' is not of type 'boolean'

Am I looking at a bug or am I doing something wrong?

I do have a great workaround: First, create the image without the 
protected flag. Then:

$ openstack image set --protected myimage2

This works.
