Error when saving HStoreField using Admin: TypeError: expected string or buffer

I have a simple model:

class TestModel(models.Model):
    test_store = HStoreField()

I edited the migration for this model per the HStoreField docs.

I have no trouble creating an object with test data {"foo": "bar"}, and in the Admin, the field for test_store displays the value as such, but when I try to save it with the Admin, I get the following error:

TypeError: expected string or buffer

Why?

I'm using Django 1.8.3 and Python 2.7.9

Hint: It seems like it's passing the data as {u'foo': u'bar'} and running into issues with the JSONDecoder:

    def decode(self, s, _w=WHITESPACE.match):

        """Return the Python representation of ``s`` (a ``str`` or ``unicode``

        instance containing a JSON document)

        """

                    obj, end = self.raw_decode(s, idx=_w(s, 0).end())

 ...

        end = _w(s, end).end()

        if end != len(s):

            raise ValueError(errmsg("Extra data", s, end, len(s)))

        return obj

    def raw_decode(self, s, idx=0):

This error occurs due to the fact that in json.load() passed a variable of type dict(). This bug is fixed in next django release. I apologize for my english, i used google translate.
