Wow! I can't imagine what you've done to the Waterfall display to make that
usable :).

That exception makes me think that it is a compatibility issue between the
installed versions of Twisted and zope.interface . If I had to guess, I'd say
your zope.interface is too old.

Check the README on that Twisted Conch package and see what version of
zope.interface they recommend. The dependency graph might be Twisted-Conch ->
Twisted-Core -> zope.interface . It's also possible that the issue is the
other way round: that you have a new zope.interface but an old twisted.conch
.

Let me know if that doesn't do it and we can investigate further.

cheers,
