I solved my own problem... I setup a custom notification to fire on the action:post.save hook and I was using the same default standard format for the notifications nid value. Basically I was firing off a notification with the same nid as the notification that auto generates when you post a new topic.
I already re-installed onto a new server. I was only testing .. If I do reproduce I will make sure to provide stacktrace. I do appreciate you looking into this. I will make sure in the future that I can provide more details.
