py-bittorrent/twistedCore broken on 8.0?

[Kris Kennaway]

Hi,

I am trying to use the python bittorrent tracker with python 2.5 and 
FreeBSD 8.0, but I am getting a lot of errors from the kqueue reactor in 
twisted.

pointyhat# bittorrent-tracker
track: create_serversocket, port= 80

exceptions.OSError: [Errno 9] Bad file descriptor
[...]

i.e. just it is getting exceptions when doing nothing at all, so it 
seems to be completely broken.

Have you tried this, or do you know where to begin looking at what might 
be wrong?

Thanks,
