It's hard to say without seeing all your code, but I notice PyUnit 0.3 
in your traceback.  If that's the PyUnit I think it is, PyUnit 1.4.1 was 
released 16(!) years ago, and has been in the standard library as 
unittest since version 2.1.  Are you running ancient versions of your 
test infrastructure?
