[Twisted-Python] trial internals help?

[Wilfredo Sánchez Vega]

  I took a stab at porting trial to use twisted.logger (http://tm.tl/7863) but I have a test failing:

	twisted.trial.test.test_reporter.TestErrorReporting.test_hiddenException

  I don’t quite know what that test is doing.  I added some additional output on my branch (branches/log-trial-7863) but that didn’t make me any smarter.

  Is anyone familiar with this code able to explain how I may have broken it?
