Hm, I can't reproduce it with current CVS of PyObjC, neither with Python
2.2 nor CVS Python. A lot has changed since 0.8, and I think it's time
for a 0.9 release...

I _did_ manage to get a crash this way:

- start TelnetServer like you did
- open a telnet session (works)
- type cmd-. or ctl-C in the window running the server. This does
nothing (not surprisingly...)
- type return in the telnet window.
Boom goes the server process:
