--- Comment #14 from Andrew Eikum aeikum@codeweavers.com --- No, it's just a bug in winegstreamer or another dshow component. You weren't seeing it before because winegstreamer wasn't being built. Since we updated winegstreamer to support gstreamer 1.0, it is now being built more often, so you are encountering this bug.
