KeyError on Content_Type when raising HTTPUnsupportedMediaType

[lucas03]

hi,
I am checking content type in middleware, and if it is not application/json, I raise HTTPUnsupportedMediaType exception.

Body template for HTTPUnsupportedMediaType:

body_template_obj = Template('''\
The request media type ${CONTENT_TYPE} is not supported by this server.
<br /><br />
${detail}''')

Traceback:

KeyError: 'CONTENT_TYPE'

Is that expected and I should not raise that Exception if content type is not set?

That is not expected I wouldn't think. Let me take a look at this before I cut 1.8 and I will see about getting a fix in.
