New submission from neoone:

Initialization of member variables with lists leads to strange 

The list object is common to each instance of that class.

File attached results in:
[] [] <__main__.Proof instance at 0x00BA7120>
['STICKYARRAY'] [] <__main__.Proof instance at 0x00BA7148>

So the initialized list a is the same in both instances.
Behaviour has been tested on 2.3 and 2.5
