Google App Engine Apptrace Error

I am trying to profile my GAE application using Apptrace When I try to do so, I get the following error

Traceback (most recent call last):

AttributeError: class rnapar_2 has no attribute '__class__'

The error shows up if I have a class object in my code. What should I change ?

It was an issue with old class type. The bug is fixed in Apptrace Version 0.2.2
