I can't see it but it can be two things: botton delaminating( less probable) or just a hair line crack with the glue under the rear sonson...yes you must solve this problem.using a dremel with a small bit along this crack ,clean it carefully with degreaser and fill it with epoxi slow cure to avoid water or oil contamination.I had a similar problem but in the transon where the rudder is fixed.
