Maybe reach out to Vivente as I'm sure they'd a] be interested in being aware and b] may have some input/advice regarding how to move forward with this. Personally, and just based on that one pic, I think that frame is probably toast.
Yes, I'd go along with the suggested contact with Vivente. Such a failure would have to be very rare and of significant interest to the manufacturer I would imagine. How old is the bike btw? Short of being involved in crashes, even old CroMo frames should remain good for many dacades, it's one of the advantages over newer technology.
Might be worth a Google search to see if anyone else had had a similar failure.
