SessionBase loses multiple values for list when encoding QueryDict objects

[tymofiy]

The testcase:

from django.http import QueryDict
from django.conf import settings
settings.configure(DEFAULT_CHARSET='UTF-8')
q = QueryDict('city=1&city=2')
q
# <QueryDict: {u'city': [u'1', u'2']}>
from django.contrib.sessions.backends.base import SessionBase
s = SessionBase()
str = s.encode(q)
s.decode(str)
s
# <QueryDict: {u'city': [u'2']}>

Reproducable in 1.0 and Trunk.

This looks like what was fixed in r10240, what version are you testing against?

Actually yes, works fine in Trunk.
