This is strange, though it can likely be explained by someone more
familiar with Woven's underpinnings (Donovan?).

However, I feel I should repeat some of what JP said earlier:

If you include A) some example code that you're using, B) the traceback
you get when you hit the exception, or C) a general description of what
you're trying to do, you are more likely to get poignant advice.

In general, for problems like this, I always try IRC first (#twisted in
irc.freenode.net). If nobody there can help, then I post to the list.
There is often someone available who can help you figure out what's
going wrong.

Please post some sample code and a traceback, and it will be much easier
to determine where this error is happening (and why).
