'Some annoying stuff can pass three-tuples to addError instead of
Failures (like PyUnit). The wrapper, of course, handles this case,
since it is a part of L{twisted.trial.itrial.IReporter}! But it does
not convert L{DirtyReactorAggregateError} to warnings in this case,
because nobody should be passing those in the form of three-tuples.'
