When using the admin site, gibberish can be entered as the lookup
parameter, at least with the change_view and the delete_view, which causes
an error. The trace that is sent to me is as follows:
{{{

It seems that this error only occurs when using a inherited object. The
Customer object in my project is defined as follows:
{{{
class Customer(Contact):
language = models.CharField(_('language'), max_length=5,
choices=languages, default='nl')
(etc)
objects = ContactManager()
}}}
Other inherited objects seem to have the same issue.
This issue is quite low-priority, as only the admin site is affected and
this only results in error mails to be sent when an user fails with its
url. It's not a security leak.
