Commit efa1bb1 introduced changes to LazyDocumentMetaWrapper which is now throwing the following error for us.

Any ideas?

Sorry for the late answer. My Internet provider decided to stop working for a couple days.

The above commit should take care of your issue and hopefully not introduce new issues. It's a bit messier then I would have liked because I'm in the process of cleaning up mongoadmin for Django 1.6.
