This Gist is just a minimal repro of a bug (I think) in Django's LiveServerTestCase.

Once a site has some static files (eg CSS), then clicking on a link produces an ugly uncaught exception from the LiveServer thread, like this:

Exception happened during processing of request from ('127.0.0.1', 1925)
Traceback (most recent call last):
  File "c:\Python33\lib\site-packages\django\test\testcases.py", line 1035, in _handle_request_noblock
    self.process_request(request, client_address)
  File "c:\Python33\lib\socketserver.py", line 332, in process_request
