I'm using the Twisted 2.0 pre-alpha that was sort of released a few days 
back (as in the tarballs were stuck up on radix's page).

Pretty sure about that one. Near the top of my main .py file, before 
Cheetah has a chance to get at anything, I have an "import WebKit" to 
make sure that WebKit is installed safely.

I added some more logging statements in Python to narrow the problem 
down to reactor.listenTCP(....). So, this is after the cfreactor has 
been installed, but before reactor.run() was called.

Here is the full backtrace from gdb. It doesn't tell me anything, but 
maybe it will say something to you:
