I don't know but am I reading this right, you said it occured while reflexing the tips, right? If it came from reflexing it is really not a fret just a crack. Can you post a pic? If it is near the non bending tip, throw some super glue in it and you will be fine. I have had this happen to me more than once and just used some super glue and everything was fine. If it is due to compression failure (bending tomuch in one spot) then the other guys suggestions are the way to go.
