order_by after select_related returns empty queryset

When querying a model with select_related(), if the related model contains a field which has null rows, adding the order_by() results in an empty set. However, count() gives the correct number of records.
Foo.objects.select_related('abc').order_by('x') # returns 
Foo.objects.select_related('abc').order_by('x').count() #returns correct number
If I fill the null rows with data, the problem vanishes.
This further leads to a "TemplateSyntaxError: 'NoneType' object has no attribute '_latest_transaction_cache'" in the template.
