I realize that this problem is difficult to track down, but I'm not sure 
what to tell you without more specific information about how your code 
is interacting with trial.

Is your code available somewhere?

Do you reliably see this error eventually if you use trial --until- 
failure?

Exactly what version of Twisted are you using?

What reactor do you typically run your tests under?

Not sure that I'd be able to tell you what's going on even with an 
answer to all of these questions, but they'd be a start :).
