Try a different type of debugger.

This one does not need you to set any breakpoints. It records the
entire run. Handy, if you don't know where to start.

Run the program once and after that all the runtime data is available
to you. Which means you can jump to any point in the run and verify
the code against runtime data.

The user interface is the python code itself viewed inside a Firefox
browser.
Scroll to a line you're interested in and click the variable.

It requires Firefox and Python 2.5.
