Bug Description

I'm trying pythoscope on iTrade to get the hang of both.
While pythoscope starts generating tests, it seems to go fine for a while, then it crashes when it reaches a specific module.
Removing the module fixes the crash.

cd project
pythoscope --init
pythoscope *.py

Confirming bug in current trunk.

Pythoscope fails during test generation for module itrade_logging.py taken from iTrade release 0.4.6.

This bug is related to itrade_logging.py using nested arguments, for example in formatException method of the myColorFormatter class:

> def formatException(self, (E, e, tb)):

Work on this bug is being done in the itrade-fixes branch.
