Worked: 2.78a, 2.77a

Short description of error
Single render or F12 doesn't want to render at all, and Animation render kind of working OK, however it misses first frame from sequence (if render start is equal to first image in sequence) and doing it nice, when render start is 0 . All of this worked in some previous versions.
