more detail, I a python module called 'runtests', it has a method 'test_suite()' that returns a TestSuite.

I run tribunal:
PYTHONPATH=.:../tribunal ../bin/tribunal
and enter
runtests.test_suite
in the bar, click run, and that traceback occurs.

Turns out this was an upstream twisted trial bug that jml has hacked on last week. Closing it here as irrelevant noise :)
