Okay, I put in the set_trace, and this is what I found:

(Pdb) l
220             else:
221                 method="GET"
222             if self.addr:
223                 import pdb
224                 pdb.set_trace()
225  ->             self.server.logger.log (
226                     self.addr[0],
227                     '%d - - [%s] "%s %s" %d %d' % (
228                         self.addr[1],
229                         time.strftime (
230                         '%d/%b/%Y:%H:%M:%S ',
(Pdb) whatis self.addr
<type 'string'>
(Pdb) p self.addr
'\004\010\204\364\377\277\226y'
(Pdb) p self.addr[0]
'\004'
(Pdb) p self.addr[1]
'\010'

Well at least we know where the ^D is coming from, but what is self.addr
supposed to contain, a string representation of the IP address of the
client?
