12769	Queryset.query pickle fails if fields have lazy translations in field declaration params.	Jani Tiainen	nobody	"If declared model as:

{{{
from django.db import models
from django.utils.translation import ugettext_lazy as _

class TestModel(models.Model):
    name = models.CharField(_('name'), max_length=12)
}}}

Using query pickle like:

{{{
from models import TestModel
import pickle

qs = TestModel.objects.filter(name__contains='foobar')
        
s = pickle.dumps(qs.query)
}}}

Fails with exception:
