It has something to do with console change not with suspend. So the easiest way confirm the issue is to run a video with Totem (xv) and close it. Then switch to console and back. If you are lucky you got no gray rectangles (Bug # 127101) and come back to desktop. Now start another video with Totem, which should have a black video window, let it run for some seconds and then close it. System should freeze. Maybe you have to wait some seconds longer for video play if nothing happens.
