12855	QuerySet.__or__ has bad behavior in the presence of extra	Alex Gaynor	nobody	"If you do something like
{{{
    q = Model.objects.extra(where=[""some stuff""]) | Model.objects.filter(c=d)
}}}

In this csae the where clause of the 2nd queryset gets lost because of the way they are combined.  This is a symptom of the fact that extra where stuff is basically tacked onto the end of a queryset after the fact."		closed	Database layer (models, ORM)	dev		fixed			Accepted	1	0	0	0	0	0
