Went a step further and just removed QLeftOuterJoins. Thanks! Committed in r11814.
Removed calls to deprecated QAnd and QOr from QLeftOuterJoins
Review Request #484 — Created Aug. 5, 2008 and submitted
These were deprecated in django r8191 per django #7830 (http://code.djangoproject.com/ticket/7830)
Not sure if djblets has unit tests or how to run them.
