[Twisted-Python] no 'headers' in server.Request instance problem

[Jon Dyte]

with mozilla build

sending a request to a quixote/twisted server (actually a modified
Andrew Kuchling Example), I get the following error

Installing SelectReactor, since unspecified.
__main__.QuixoteFactory starting on 8098
Traceback (most recent call last):
  File "/sw/release/python/lib/python2.2/site-packages/twisted/internet/default.py", line 347, in doSelect

exceptions.AttributeError: QuixoteTWRequest instance has no attribute
'headers'


The object QuixoteTWRequest is defined 

class QuixoteTWRequest (server.Request):
      ......

it looks to me like on some execution path thru http.py (dataReceived,
lineReceived) etc etc the headers slot of the server.Request object
doesnt get set. which would appear to mean requestReceived has not
been called as this sets self.headers to an empty dict at least.

The headers sent by the browser are :-

I'm pretty new to Twisted, so I might be missing something here, but
the script works with lynx and netscape 4.76.
