Description (last modified by Alex Gaynor)

This occured immediately after I applied the 1.1 release onto a site that was previously using a beta 1.1 version from about 3 months ago. Sorry, can't be more exact.

Traceback (most recent call last):

Please ask on django-users or #django channel and reopen with more info if it is a Django bug. And please provide detailed steps to reproduce this bug (including models). Step by step described bug is easy to reproduce and fix.

This was likely due to the server running a mixture of code from 1.1 Beta and 1.1. BaseQuery.extra was added in [10648], which was post-beta. It appears the server is running with a django/db/models/ from 1.1 (since it's expecting BaseQuery to have an extra attribute) yet a django/db/models/sql/ (where BaseQuery lives) from 1.1 Beta, before BaseQuery had this new attribute.
