On the right side of the photo (rear of the bike), the crack appears to extend through the brass joint filler, so I would be very concerned that the joint would be in the process of failing.
If it is actually the joint and not the tubing, it is quite possible that it could be repaired quite cheaply by a good frame builder. See if there are any local to you.
Ah yes, it is the seat tube, i had a brainfart. I wasnt sure if it was a shadow caused by the light i shined on the brass filler area but i will take it to a framebuilder by me to get it checked out. Thank you very much for your reply.
