I expect that this is due to the difference in the signature of the 
constructor of 'object' in Python 2.2 and Python 2.3.


Python 2.2.3+ (#1, Jul  5 2003, 11:04:18)
[GCC 3.3.1 20030626 (Debian prerelease)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> object(1, 2, 3)
<object object at 0x8168218>


Python 2.3b1 (#1, Jun  4 2003, 16:23:13)
[GCC 2.95.4 20011002 (Debian prerelease)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
 >>> object(1, 2, 3)
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
TypeError: default __new__ takes no parameters


The solution is to make sure you write an __init__ method that accepts 
the appropriate arguments.

This is often the case in unit-tests where a dummy class is written 
using the minimum lines of code that will actually work.

Unfortunately, this minimum is slightly greater in Python 2.3.

I think pychecker picks up this problem.
