If a timer is running while it's deleted it is still register with the event dispatcher. This causes a segmentation fault when the timer time-out and its signal is emitted. Fix this my stopping the timer when it's deleted. Signed-off-by: Niklas Söderlund <niklas.soderlund@ragnatech.se> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
