 If I have such construction:

 {{{
 #!python
 # models.py
 class BoolTest(models.Model):
     NO = False
     YES = True
     YES_NO_CHOICES = (
         (NO, 'no'),
         (YES, 'yes')
     )
     completed = models.BooleanField(
         default=NO,
         choices=YES_NO_CHOICES

 # admin.py
 class BoolTestAdmin(admin.ModelAdmin):
     list_filter = ('completed',)
 }}}

 and I use filter results in Django admin, then this URL is generated (for
 `no` and `yes` choices):

 .../admin/appname/booltest/?completed!__exact=False[[br]]
 .../admin/appname/booltest/?completed!__exact=True

 The !True/False is taken as string (not converted 'True' -> True and
 'False' -> False), non empty strings in Python are considered as True, so
 the final SQL is for both choices:

 SELECT `appname_booltest`.`id`, `appname_booltest`.`name`,
 `appname_booltest`.`completed` FROM `appname_booltest` WHERE
 `appname_booltest`.`completed` = 1  ORDER BY `appname_booltest`.`id` DESC

 I think, that instead of !True/False there should be 0/1 in URL
