Content-Type error

[jmcannon]

I ran into this bug while making a DELETE request to my django-livesync enabled backend powered by django-rest-framework.
Here's a trace:

Traceback (most recent call last):
  File ".../django/core/handlers/exception.py", line 34, in inner
    response = get_response(request)
  File ".../livesync/core/middleware.py", line 12, in __call__
    return self.process_response(request, response)
  File ".../livesync/core/middleware.py", line 16, in process_response
    if settings.DEBUG and 'text/html' in response['Content-Type']:
  File ".../django/http/response.py", line 144, in __getitem__
    return self._headers[header.lower()][1]
KeyError: 'content-type'

Someone already fixed it in a fork: src-r-r@55555f6. Would be great to see the fix in the npm package.
