Sorting dictionary keys lead to incorrect dictionary access

[GoogleCodeExporter]

With console_fr.html:

x = { "Z" : 26, "A" : 1 }
for i in x.keys():
    print(i, x[i])

n = x.keys()
n.sort()
print(n)
for i in n:
    print(i, x[i])

Reports:

Z 26            <= correct
A 1             <= correct
['A','Z']
A 26            <= wrong
Z 1             <= wrong
<done in 26 ms>

The given program is invalid when testing with an old python3 (3.1.2)
Traceback (most recent call last):
  File "z.py", line 6, in <module>
    n.sort()
AttributeError: 'dict_keys' object has no attribute 'sort'

Possible workaround when using dictionary keys:
n = list( x.keys() )

By the way: same issue with "values()"

Thanks for the report, that's very helpful
The bugs should be fixed now (version 20121228-090636) : keys(), values() and 
items() return an iterator object, without a sort() method
I close the issue
