I still can reproduce it (see below). I think the patch only solves the problem
for reverse playback. In this bug there's no reverse playback involved (if I
understand what reverse playback means, rate < 0?).

My patch in comment 10 I think solved the issue for both cases, but as
Sebastian pointed out in comment 12 that patch is not correct.
