What steps will reproduce the problem?
1. run trunk\misc_scripts\deep_copy_bug\eqrm_flags.py

What is the expected output? What do you see instead?
This is the  error;
 vulnerability_set = copy.deepcopy(self.vulnerability_set)
...
    return cls.__new__(cls, *args)
TypeError: instancemethod expected at least 2 arguments, got 0

python2.5 eqrm_code/test_structures_vulnerability.py * this fails, due to this 
bug
python2.5 test_all.py doesn't.  Why?

I didn't work out why.  But I implemented the fix suggested in stack overflow.  
That fixed it. revision 1189
