QueryDict serialization into session

[EralpB]

We are having an issue with QueryDict serialization, one system is Linux the other one is Windows.

---

dict2 = {'a': 'one', 'b': 'two', }
qdict = QueryDict('', mutable=True)
qdict.update(dict2)
print qdict
request.session['lal'] = qdict

#and then in another view I do:
print request.session['lal']

---

This outputs:

Linux:

<QueryDict: {u'a': ['one'], u'b': ['two']}>
{u'a': u'one', u'b': u'two'}

Windows:

<QueryDict: {u'a': ['one'], u'b': ['two']}>
{u'a': [u'one'], u'b': [u'two']}

Why the difference?

Could you write a test for Django's test suite that demonstrates the issue or provide a minimal project that we can download to reproduce the issue (ideally, that doesn't have any third-party dependencies)?
