#16714: Can't list_filter across a relationship on a SmallIntegerField

If you have a SmallIntegerField on a model that is related via a foreign
key then you can't use that field as an option in list_filter. Doing so
gives you the correct distinct options in the list page sidebar, but if
you try to select any of them you receive a 302 redirect to /?e=1, as if
you had used an unexpected query-string parameter.
Here's a small example to try yourself:
{{{
# models.py
from django.db import models
class Rel(models.Model):
year = models.SmallIntegerField(default=2010)
class Src(models.Model):
rel = models.ForeignKey(Rel)
# admin.py
from models import Rel, Src
from django.contrib import admin
class RelAdmin(admin.ModelAdmin):
model = Rel
list_filter = ('year',)
admin.site.register(Rel, RelAdmin)
class SrcAdmin(admin.ModelAdmin):
model = Src
list_filter = ('rel__year',)
admin.site.register(Src, SrcAdmin)
}}}
I'm running Django 1.3, MySQL 5.5, on Arch Linux.
