Summary: params with default value in __init__ method doesn't work...

Initial Comment:
The handling of constructor parameters with default
value have a problem when called many times...

It is like the value is cached or something. 

This is very annoying and easily reproducible :-(

Below is the output of what I get on win32 2.2.1
(attached is the code to reproduce)

Sincerly,
Vlry


output:

BUG using params with default params...

test1= test()
0) __init__ []
1) self.params= []
2) self.params= []
3) self.params= ['default']
test1.getParams() => ['default']
test2= test()
0) __init__ ['default']
1) self.params= []
2) self.params= ['default']
3) self.params= ['default', 'default']
test2.getParams() => ['default', 'default']
test3= test()
0) __init__ ['default', 'default']
1) self.params= []
2) self.params= ['default', 'default']
3) self.params= ['default', 'default', 'default']
test3.getParams() => ['default', 'default', 'default']

OK using initialized params

testA= test(['A'])
0) __init__ ['A']
1) self.params= []
2) self.params= ['A']
3) self.params= ['A', 'default']
testA.getParams() => ['A', 'default']
testB= test(['B'])
0) __init__ ['B']
1) self.params= []
2) self.params= ['B']
3) self.params= ['B', 'default']
testB.getParams() => ['B', 'default']
testC= test(['C'])
0) __init__ ['C']
1) self.params= []
2) self.params= ['C']
3) self.params= ['C', 'default']
testC.getParams() => ['C', 'default']
